Help! My 18month old keeps waking

[MamaCross19]

Can anyone give me any suggestions as to why my 18 month old keeps waking at around the same time every night for 1-2hrs???
She also uses to have around 2 hrs nap in the nap but now she wakes after 1 hr.

It might be the dreaded split nights, caused either by developmental milestones or by trying to get your little one to sleep more than they need to. At 18 months we had to cut the nap shorter to stop split nights. Sounds like the nap is already short at 1 hour though - what time is the nap, what time is bed time, and when does your little one wake up? If the split nights are caused by developmental stuff then you might have to ride them out unfortunately. But if caused by aiming for tomorrow much sleep then cutting sleep down a bit may well fix the issue. I think huckleberry give some good advice on split nights.
