My dd has just turned 16 weeks and is atm exclusivly breast fed. She has ebm while I'm at work 1 day and 2 evenings per week. She normally feeds every 4 hours (7,11,3,7) and sleeps from 8pm to 7am. She will drink 10oz of ebm in a feed and has recently started waking up and downing both boobs at night. I'm thinkng about putting her on formula as I can't express more and she is less interested in breast feeding and I'm not sure how much she's getting. She won't spend longer than 10 minutes per boob now. Also she has slowed down with weight gain and did not put on in the last fortnight. She is cranky in the evenings despite having good naps. Is she ready for solids or should I put her on formula or keep trying to up my milk supply? Oh yeah, she was 2 weeks late and a big girl too (9lb). Any advise welcome I'm confuuuuuuuused!
