my dd pfb dropped from 50th percentile at birth down to 2nd at 4 weeks. she was tongue tied and had trouble breastfeeding.
I started giving her formula then as HV told me I was "starving my baby". (wish i'd known then what i know now).
have really struggled with bf, had all kinds of problems and she is probably 90% ff (about 25oz a day a 4 months - HV tells me she should be on 40oz). i have always been v. unhappy about ff, and still bf as much as i can and just top her up.
today dd is up to 75th percentile HV says she's fat and i should stop doing the bf and just give her formula!!
aaaaaaaaaaarghhhhhhh. grrrrr.
at least now i know not to listen, which i didn't know when she was 4 weeks old
