Hi wandering if anyone can help with advice. I have a 7 month old and she has about 3-4 breastfeeds in the morning ( roughly 3am 7am 11am) then in the afternoons i give her formula. I try offering her 200ml around 1pm 5pm and 8pm and it isn't working. She only takes 80-100ml each time so i usually end up giving about 5 bottles and wasting so much formula. she also has solids 3 meals a day. has anyone been successful combining both breast and bottle feeding and able to suggest anything. she spends a lot of time crying in the afternoons (even when i hold her ) and settles down after a small drink of formula. I'm planning on returning to work 1 or 2 afternoons a week so was hoping this combo feeding might work but so far its not. any advice appreciated thanks
