Ds is 3 and a few months. Generally is a brilliant wee sleeper, active during the day and lots of fresh air etc.
This week nothing has changed with his routine but his sleep is suddenly up the left. He usually goes to bed at around 7/7.30pm (earliest I can get him to bed with work) and wakes at around 7.30/8 usually by himself.. he's not napped since he was 1.5.
Now he's going to bed really well as normal but then suddenly waking up at midnight every night and having a really hard time going back to sleep. He's been awake tonight for almost an hour and a half. He's clearly tired but can't wind down, in great form, doesn't want cuddles etc but just unable to sleep. I have a dose so I tried giving calpol just incase he's under the weather too but its made no difference. Room is dark, cosy and quiet. Routine has been the same as always and he was quite happy dozing over.
I'm totally exhausted and not sleeping well with this cold as it is so I'm struggling, have had to use my wfh lunch break for naps I'm so tired. What is happening and how can I make him sleep through the night again??
