Hi Mommies, i return to work for 2mths already. Been giving DS BM expressed the day before n he've been doing fine. Recently, i heard from friend frozen EBM kept for more than 1 mth will loss it's antibodies, so i started feeding DS the frozen ones in the past 1 week, n now DS got so much wind in his stomach it's bloted like balloon.. Is it due to the frozen EBM?
