I gave my 3 month old one bottle of formula for the first time yesterday, she's an ineffective feeder and so her BF take over an hour each so I am slowly weaning her onto formula for some feeds to allow us more time for play, naps etc.
She had her first bottle of formula at 6pm taking just 70ml, we paced fed. She seemed fine taking it but come 10pm and she wakes screaming with wind, she has cried all night. Me and my partner have had to take it in turns to sleep or hold her.
Is it the formula that's done this? What have we done wrong?
