Those with formula fed babies, how long have their growth spurts been? S is almost 10 weeks, and this has been our most challenging week since the first couple. He was vaxed on Thursday wasn't fussy, just slept a lot Thursday and Friday and was a little low on ozs. For a while, he'd been averaging 27-28 ozs/ day, but since Sunday he's been up to 31-34 every day. He's also been super fussy and not sleeping so great. Sometimes up every hour or 2 at night just wanting to be held. He hasn't had a spurt last this long or be this intense. Wondering if it's something else? Apologies for lack of paragraphs, on mobile. Obligatory squish pic for reading.
