My LO., 7mo...she was exclusively breastfeed... but now as I am returning to work I tried to give her formula .. she takes expressed breast milk in avent bottles nicely but she rejects all sort of formulas I tried lactodex, lactogen and nan pro stage 2... pumping takes a lot of time... I use luvlap adore electric pump it literally expresses 1onz in 20mins... so which formula would taste near similar to breast milk or which pump I should buy which can fasten the process??? pls do help
