My usually smiley happy DS had his 8 week injections today. He wailed at the time as to be expected then was fine, came home had a feed and a big nap. Since waking up he’s been inconsolably crying. I’ve tried skin on skin, tried to feed him, given him his second dose of calpol, cuddles, taking him out in pram but he is non stop wailing. He’s breastfed and I keep offering him a feed (he hasn’t fed since before his big nap so I’m sure he must be hungry) but offering him the breast makes him cry even harder. Is this normal, when will it pass? He is usually such a happy baby and this is breaking my heart. Any suggestions?
