DS had his 1 year vaccinations two weeks ago. He was fine at first and then over the last 5 days he’s developed a rash, not eating, very unsettled and grumpy, and not sleeping. The nurse said it’s all normal side effects. However he’s hardly napping and for the last 5-6 nights has been awake for a minimum of 3 hours in the night and I’m running on empty. Tonight has been on another level, he woke at 1am and I haven’t been able to get him back to sleep since and it’s now 6am. He is clearly shattered and beyond overtired but I’ve tried everything. Putting him in our bed, rocking him, he’s refused milk completely. He usual self settles on his own for both naps and night sleep but he screams and screams tonight. I’ve tried lying on the floor next to his cot. Nothing is working and I don’t know what to do. DH is getting up shortly to take over while I hopefully sleep, we’ve been having to try and sort this in shifts, but we’re both key workers and desperately need some sleep. I’ve brought him downstairs and he’s happily playing on the floor. I assume that he’s going to conk eventually but how long do I let him sleep for today to try and avoid the same thing happening tonight? I’m feeling very low. Up until this last week he was a very good sleeper and now I feel like this might never end
