Background - toddler had awful split nights from 12-17m but we managed to get rid of them with lots of routine tweaks and being strict eg getting him up at 6.45am, sleeping around 8pm and at that time a 90 min nap 12-1.30pm. We were always told that 9 times out of 10 split nights are due to too much sleep or trying to make kids sleep too much overnight and not enough sleep pressure. We were told to think of sleep pressure like a fuel tank - wake up full, depletes during the day and the nap tops it up but you want an empty tank by bedtime to keep them asleep all night. Anyway, I digress… we’ve had him sleeping all this time and whenever we felt bedtime was getting later/harder we cut the nap in 15 min increments and just before Xmas we cut it down to 45mins which is where it’s remained.
but over the last fortnight or so the split nights are back with him awake 2-4.30am and it doesn’t help that during the good sleep times I got pregnant again , now around 20 weeks.
I don’t think the nap is ready to go as he’s so shattered for it come midday/12.30 and falls asleep within 5-10mins.
is this a phase that will sort itself with no routine changes? Or what do I do? I’d be fine if he slept 8-6 and then a 45 mins nap which doesn’t seem like too much for his age? Or does he need more sleep? I’m not sure offering more day sleep is right either… help 🤣
