btw, pls do NOT mix diffe FM together. might cause your baby to hav diarrhoea.. and honestly, for FM, you will hav to let your girl try out diffe one. cos diffe babies need diffe FM. some might say this is good but other babies might not suit..
yup, i also heard that Nan is closer to breast milk and easier to digest. for dear son, he has been drinking Similac since 4mth old..
for changing FM, pls change slowly, replace 1 feed 1st, for around 2-3 days. then replace 2 meals for 2-3 days, and so on.. =)
