I think it's still too early to tell definitely, but I *think* it was the formula after all. We went through a night (a 2am and a 6am changing/feeding) with no poopy. Now I just have to hope the soy-based isn't going to constipate him or he'll be 10x more miserable than he was yesterday. At the doctor's suggestion, we're slathering his little bum with "Boudreaux's Butt Paste" which seems to be helping a LOT. And because of the lack of poopy, his butt isn't nearly so raw and irritated as it was yesterday.

My husband had to be on soy formula (don't remember the reason) but is fine with dairy products now, so we're hoping the same for Aidan. I wouldn't want him to be lactose-intolerant his whole life.

Thanks for all the prayers but don't stop yet!
