I am wanting to see if my hunch is right. When Michael went from strict boob to supplementing with formula, I used any old kind of formula: Similac, Enfamil, store brand etc and the changes never seemed to faze him. I finally settled on the Sam's Club brand. We were running low last week and when I went shopping locally (because the closest Sam's is 45 minutes away) I grabbed a can of the store brand which Michael had had before and started using it at home on Thursday. For the past 4 nights, Michael has woken up crying two hours after he went to sleep. This is not like him. He usually wakes up in the middle of the night for his feeding by cooing at first and then will "yell" if we do not move fast enough. He vacuums down 8 ounces and is usually asleep in 30 minutes or less. He has also pooped his brains out the last three days. Sunday afternoon it was up past his armpits. (Tim had to change that one and is still having a trauma response, constantly smelling baby poop.) I am thinking that the formula change is now upsetting his tummy and causing gas pains. His little legs will get stiff and he can not lay still when he is trying to go to sleep. Tim was at Sam's Monday and picked up two cans but I did not think that this might be the cause until after we had used the entire store brand can. Thanks for the input.
Re: To FF mommies
I only switched once, and I did it gradually as well. When Sydney had gas pains, she would pull her legs up. Not really stiffen them.
Hope he feels better soon. Poop up to his pits, huh? That doesn't sound fun for anyone!
