My 7 month old bub has started actually eating solids the last few weeks. He has always been a terrible sleeper, since he started eating his sleep has become soooo much worse. He wakes up sometimes every 10 mins, very upset, arching his back for hours at night. When I pick him up and put him upright he usually eventually let's out a huge burp or two and pulls faces like there's something awful in his mouth. This never happened before solids.
He isn't waking from hunger, he still demands a breastfeeding every 2-3 hours at night.
Any ideas? Does this sound like reflux? And why would it only start when solids start?
