Is switching from good start formula to similac formula a good idea?
Q. I have a 5 month old baby. I still breastfeed at night but I started supplementing good start formula at 2 1/2 months because of work. I have talked to my doctor multiple times about his spitting up,gassyness, and fussiness. He told me to keep using the formula because his stomach is still getting used to it. So I changed to similac formula early sheild. Was that the right thing to do?

A. heads up you are the mom if you think that the good start is not working for your child then you have all rights to change it. 2.5 months is a long time if your child still is not adjusting good then I would change it. It took me 2 formulas with my first child and started my 2nd child on the same as the first then came #3 and it took 4 different kinds ended up with allementum and with my daughter i used carnation good start. Don't ever double question your ability as a mother to know when your child needs something different to work with!

What is the formula of finding the shortest formula leading to a huge number?
Q. For example, what is formula that leads precisely to number 9342352, and what is the formula on which you have found it? Formula122 Exactly, by formula I mean what MathMan TG has already answered (thanks!). But, I need to find the shortest formula. Look, the first formula you have put, in fact can be shortened to 25456 * 367. More precisely i look for something like: x at y power * z or + z If my number 9342352 has 7 characters in total, I need a formula that in total will have less characters. Is that possible?
Asked by solicromania - Sat Feb 7 16:11:18 2009 - - 1 Answers - 0 Comments
A. What do you mean by formula ? You can factor the number: 2 * 2 * 2 * 2 * 37 *43 * 367 by various methods, the most basic of which is dividing by successive primes. Or 2 * 3 * 3 * 3 * 173 * 1000 + 2 * 2 * 2 * 2 * 2 * 11 which can be shortened to 54 * 173000 + 32 * 11 Along with unlimited other possibilities.

What is the difference between toddler formula and baby formula?
Q. I have switched my 4 month old Baby Boy to Baby's Only Dairy Toddler Formula because it seems to be the most organic formula out there, and because I have compared it's ingredients to other infant formulas and it seems to be equal. Does anyone know any medical facts or information about this?
Asked by Kurt's Mama - Wed May 20 01:21:35 2009 - - 4 Answers - 0 Comments
A. No, I think they are quite similar. Baby's Only is an "organic" formula, which mostly markets itself as "toddler" because the company does in fact believe, as do medical experts, that breast milk is far and away the most healthy thing to feed an infant. Infants should be getting breast milk, not formula. At least, that is what I have heard about the company. Otherwise, I would just wonder if it contains DHA/ARA and iron supplementation. There are no other differences.

How much formula do you buy a month for your infant?

Asked by Baby #1 due March 25th...yayyy - Wed Oct 21 10:23:32 2009 - - 4 Answers - 0 Comments
A. First breastmilk is best and you really don't need any supplementation. The baby could get nipple confusion and refuse to nurse. But if you are planning to pump, I pump for my daughter and feed her the milk in a bottle. (She couldn't latch due to being in the nicu for 24 hours and decided she wanted to keep feeding from the bottle). She only has to have 1 bottle of formula every other day. I almost make enough, but not quite. I give her 4 oz at a nighttime feeding. I have to feed it while she's still asleep a little or she won't take it. She wants breastmilk over formula. We use Goodstart formula because it is easiest to digest and only has whey proteins. The casein proteins in other formulas cause curdling the tummy and can cause more… [cont.]

A. Every child is different. As long as she is not in pain when passing poo, and is feeding well there is no problem. Some breast fed babies dirty their nappies at every feed some at two or three feeds. The same is true of formula fed babies. If her dirty nappies remain watery then she should be seen by a Dr and a specimen sent in case she has a gastric infection.

What is enough formula to give a 3 month old?
Q. Hello, my daughter is 3 months old and I recently increased her formula intake from 4 to 6 oz every 3-4 hours. But ever since I've increased her formula intake she sleeps alot more. She used to stay up the majority of the day but now, after every feeding she falls asleep for 1-2 hours at a time. She's still sleeping through the night but I wanted to know if this is normal or if I should decrease her intake back to 4 oz. The reason I increased her intake is because she was still hungry after the 4 oz. Thank You.

A. Formula is expensive. But you need to follow the directions for the sake of the baby. If she drinks out of it, you need to throw it away after an hour of her starting to drink from it. Since it is expensive, do what i used to do. If you make a 4 oz bottle and she usually drinks only 2 ounces, then put half in a clean bottle. This way, if she wants more after the 2 ounces, then you can just pour it into the bottle you are already feeding her. Or, if she doesnt want more, then just put the milk that she hasnt drank in the fridge for later. If she *ALWAYS* only drinks 2 oz, then only make 2oz bottles for her.

A. gross/net*100 (this will be greater than 100% because you're dividing a smaller number (net) into the larger number(gross) or what % of 500.00 is 564.38 Just switch the net and gross and this %age will be less than 100% net/gross*100

How to find empirical formula with only the mass of the reactants?
Q. I need some help with a problem for Honors Chem. II. I know the definition of empirical formula, but I don't know how to find it with just the given information. When 1.5*10^-2 g of an organic substance containing only C, H, and O is combusted in an excess of oxygen, 0.0267 g of CO2 and 0.0176 g of H2O are recovered. What is the empirical formula? Any help is greatly appreciated.

A. 1) determine the mass of carbon, hydrogen and oxygen. carbon:0.0267 g x (12 / 44) = 7.282 mg hydrogen: 0.0176 g x (2 / 18) = 1.956 mg oxygen: 15 - 7.282 - 1.956 = 5.762 mg 2) convert to moles. carbon: 7.282 / 12 = 0.6068 mmol hydrogen: 1.956 / 1 = 1.956 mmol oxygen: 5.762 / 16 = 0.3601 mmol 3) divide each molar amount by the lowest value to obtain small integers carbon: 0.6068 / 0.3601 = 1.685 hydrogen: 1.956 / 0.3601 = 5.432 oxygen: 0.3601 / 0.3601 = 1 For a simple compound we would have gotten small integers indeed... Multiplying by 12 gives a ratio of 20.2: 65.2: 12, but I don't guarantee that is the correct answer.
