DD is 21 weeks (ie 5 months next week) and I am planning to start BLW as soon as she is ready - I don't think this will be long tbh as she is already watching me intently and has had a few 'tasters' (brocolli, banana) already 
My question is what to do about BF once BLW has commenced. I'm not ready to stop entirely, but would like to maybe introduce some formula for day feeds with the aim of only BFing morning and night by Xmas. Does this sould feasible? if so, how the hell do I start, do I just gradually swap a BF for a bottle?
Also, if I do give the odd bottle of formula here and there, but then say I want to BF more at weekends, will my supply be affected or will I be able to do this?
Any advice gratefully received!
