After a difficult recovery and to give myself a little break, I have decided to introduce one formula bottle in the evening for my breast fed DS. The midwife advised me to give no more than 60ml as it would stretch his stomach, however he wasn't satisfied after this and I had to top up with breast milk! It defeated the object of DP giving the formula, does anyone have any experience with mixed feeding and how much I can give? He is a big 9lb baby!
