My LO had the 2nd round of vaccines two days ago and since then his night time sleep has gone out the window. First lot he was fine, just slept a lot. This time he's waking every hour or so unsettled and is also struggling with getting to sleep when I put him down of an evening. We've gone from 4-5 hour stretches and two feeds to what feels like newborn carnage again!
Has anyone else experienced this or have any helpful tips?
