Is the exposure to tobacco smoke during pregnancy a possible risk factor for allergy as well as urban living, indoor humidity or mould growth?

My daughter was born on 5/5/06. Following 3 months of extreme fussiness, painful cries and incolsolablility, her GI doctor put her on Neocate as an experiment (try it for two weeks and see if there is improvement). We've been on it for about 5 days now. The first two days were great! What an improvement. Now, however, she's back to being fussy, spitting up (something she never did before) all the time and gassiness. Once she spits up or passes gas she's more comfortable and stops crying/fidgeting until it starts all over again. Her doctor also has us thickening her formula with Beechnut rice cereal (a change from the Gerber rice cereal that we had her on before). Any ideas as to why she would suddenly develop these symptoms and how we might eleviate them?

My son was born at 32 weeks. He spent his first month in the NICU. When he was released from the hospital, he was just finishing up his supply of Special Care Infant Formula from the hospital and he was also getting my breast milk. One week after he got home, he was back in the NICU for possible infection, because he had projectile vomiting. Infection was ruled out and he was sent home in 3 days. He began having the projectile vomiting that landed him in the doctors office everyday for almost a week. The put him on Allimentium formula. He vomited worse on that, so they put him on Neosure Infant Formula. He still continued vomiting. Finally, I had took him to a different doctor and he ordered an ultrasound of his stomach. He had pyloric stenosis. He had to be admitted to the Childrens Hospital that same day. He had the pyloric stenosis repair 2 days later. The gastroenterologist had said my son has GERD,soy,milk, food, citric acid allergies and had put him on NEOCATE Infant Formula. He will be 1 year-old in 3 weeks, and the doctor had said about putting him on Pepdite Junior when he turns 1. I had talked to a nutritionist about EO28 Splash and she said it would be better for him to go right on that (EO28 Splash) since it is amino-based, and the Pepdite is not and is harder to digest , and also contains soy. the flavor will be grape since it has no citric acid like the orange-pineapple and the tropical fruit. Which do you prefer? Sincerly, Connie. THANK YOU!

My daughter is almost 4 months old and has a milk allergy and acid reflux. The GI put her on Neocate and Zantac about a month ago. She seems to be doing much better, but the Neocate gives her very bad gas. She's up every 1-2 hours with gas pains. She passes gas almost every time I pick her up from her crib (screaming!). Often times she wakes and doesn't want to go back to sleep....although I know she's tired. Of course all of this waking is causing her to be grumpy. Overall, things are much better than they used to be, but if we could resolve this gas issue I believe she'd be a much happier, rested baby. Smithecone which hasn't worked for us. There has to be something. Any suggestions? Have you heard of using Probiotic drops for infant gas?
