If you use any type of rice cereal gerber sells a great one with dha and probiotic.

no problem hun! the one I use, it lasts me about a month (I have 2 using it) but for one baby it will last 75 days, it's just 1/4 tsp in their bottle or food (when on solids) and it does need to be refrigerated. it takes about 2 weeks before your really see a difference. Hope it helps hun!

@twinmamma2015, thanks!

do you have a health food store near you? I give my boys Probiotic everyday since they were born.
