Formula feed


Hi mommies .. my baby turned 6 months last week and I have started him similac 2 .. he was on similac 1 and breast feeding both till now .. I still continue to breast feed along with formula ..

the problem now is since I started similac 2 , the LO doesn’t want his bottle .. also he poops after every feed .. the poop was initially solid but is a little runny since some days .. I am still breastfeeding and he prefers it over his bottle which is a surprise because since his birth he always preferred his bottle ..

is similac 2 making him sick or something ?? Should I see a dr or change formula ?? Any experienced mommies ??

P. S he is also teething and has two tiny teeth already..
