DS currently has a breastfeed first thing in the morning, again around 2:30-3 pm and then a bottle of formula at bedtime. I breastfeed him if he wakes in the night but he normally sleeps through. He eats really well (more than 3 yo DD) but isn't that fussed by milk. He's now pretty fussy when I try to feed him and only feeds for 5 mins max. I think we're done with breastfeeding which I'm fine with but could I swap to cows milk rather than formula? He's 1 at the beginning of March.
