15 month old has been asleep for 4 hours

[MidnightCereal]

She had her injections yesterday (she’s a bit older as they were delayed due to illness) I know it can make them a little off colour but she went down for a nap at 12:15ish and is still there, I’ve gone in and given her a nudge a couple of times and she wakes but just goes off back to sleep

Should I just let her sleep do you think or should I be worried?

Id let her sleep- my LO (and therefore me too) had one of the longest naps after her first set of injections.

OH I wish I’d had an epic nap too, the 3 other DC ensured that didn’t happen 🙄

I'd wake now if you want her to sleep tonight! And check her temperature.

I woke mine after 45 mins. To avoid messing with their sleep schedule. Bearing in mind the jabs, I'd wake after 1.5 hours so 2 sleep cycles. She won't sleep tonight otherwise and will then be overwrought.
