dilute it some or try 2 or 1%

That's exactly how my son was.

My son just turned 2 in April

how old is he? neither of us have any problems so its kind of weird if he doesnt tolerate it but we are all different so its very possible i just couldnt clam him down he was crying alot and i guess its because he can taste the difference ive been doing a oz less of formula every day and not its 3oz of formula and 5 oz of milk and i think he can tell. @mommyto3girls1boy

My son was like that, he couldn't tolerate milk so he was put on soy milk he just started drinking milk about 3-5 months ago
