There’s also a sleep regression that happens at this age, which could be playing a part, my daughter is currently going through it x
Could of written this myself I’ve just posted asking if anyone else’s LO has gone down hill since jabs he had his last week and this week he’s gone backwards with sleeping at night use to sleep all night now wakes up from 2 was slightly off his food yesterday had a bit of a temperature screaming for no reason I’m happy he’s had them but Jesus I’ve had 4 hours sleep last night and now have a full days work to do I can’t carry on like this
I think it’s normal after their jabs for them to be a bit messy with sleep. It will pass - thinking back to my first three boys. Might be a good idea to adapt it slightly to suit you whilst it’s happening.
