Started weaning approx 1 mth ago so well established. Always been fussy eater but suddenly fussy with the bottle as well. Roughly drinking only 12-14 oz per day (took a massive 2.5 oz just before bedtime this evening!)which I think is way below min needed. I try to persevere but she struggles and cries until I stop. Stopped bf last week which she may be reacting to?? Getting v worried, can anyone advise?
