I began feeding cereal to mine upon arrival home... My Kids were good babies, and they slept through the night, Thanks to cereal. I think that cereal will answer all your problems... My mom is the one who suggested it to me as this was what they did back when she was born, and we were born,so I did it and do not regret it... In my case none have any allergies, and did sleep all night, and my pediatrician was ok with it, and I was ok doing it...
my kids are healthy, and eat good with no allergies to food... If you do not get your answer here, try your peds.
doc. and see what he suggests and instructs.... he'd have all updated info.... My babies were good babies after starting cereal, they would get agood nights sleep and be alert the next day, & I feel it was because their little
tummies were full. I can not tell you this is your answer, but I can suggest it to you, and what you do from there is ofcourse your decision. I hope this does help you, and I hope that you follow your own heart.....
