My little one turned 1 last week, and has been having explosive frothy, floating yellow poops for the past 3-4 days now. She has them twice a day, usually in the first half of the day and then not again until the next day. She's also very gassy at night before these movements the next morning. She's pretty much exclusively breastfed, as she still isn't very interested in solids. She does get random small bits of food, but nothing substantial. Otherwise she's doing great, looks healthy and happy, nurses about 9 times a day at least and is developing fine. The only thing I could think of was teething (she had all 8 teeth by 10 months). But this is much different from her previous teething stools. Ideas???
