Emma is 14.5 months and still on Alimentum. We tried a hidden dairy trial at around 13 months with ice cream, cheese and yogurt and it went terrible. I noticed that your signature says he is not interested in eating, so is Emma. Food is nonexistant in our home and she hasn’t ate for 2 months, only a few bites here and there, so her diet is primarily formula and since milk is a no go thats where we stand. She had a bad reaction to soy at an early age so I am not ready to do a trial on that quite yet!
