DS is 15w and ebf. He is happy to take a bottle of ebm too. I'm struggling to find the time to express however, and am also going back to work in three/four months. With this in mind, I am hoping to start gradually introducing formula for daytime feeds - am hoping to still bf for first and last feed of day if possible. From what I've read I believe it's best to replace one of the daily feeds at a time, for a week, to give my body time to adjust?
As DS has never had formula I'd started 'softly softly' by offering an oz or so, followed by boob, to make sure he could tolerate it. Did this over a couple of days last week without any obvious issues, so yesterday replaced morning feed with bottle of formula. DS has been really unsettled ever since - fussing, irritable etc - and the dry skin on his tummy seems more 'pronounced' this morning iykwim. (I had eczema as a child which seemed to settle once I stopped drinking lots of milk - never formally dx'd as intolerance/allergy or sensitivity though)
I feel so guilty - was in tears last night. Problem is I don't know whether I'm attributing unrelated stuff to the formula feed and overthinking. DH is of the view that it could be something different - he's also stuffing his hands in his mouth and dribbling a lot (?teething) and I know that there's a growth spurt around now too. He's suggested we need to try again to be sure but I feel like such a bad mummy if I am inflicting this on him with formula. Can't decide on the best way forward. Does anyone have any words of wisdom and experience?
Fwiw, the formula I tried was HIPP organic...
TIA
