15month Old - Inconsistent (mainly bad) sleep

[GooglingFather]

Hey All.

My 15month old boy still not sleeping "great" (trying to be positive). He self settles fine when put to bed and has done since about 6 months but still regularly wakes at night; sometimes he fusses goes back off on own, sometimes wants a bit of water and sometimes like this evening wakes up for a solid 2hours and cries (I go in but not straight away all the time) & lastly sleeps all the way through on occasions (once/twice a week)

Room temp is fine day time naps generally good and like I say really inconsistent and no pattern - it's been going to long enough to not be a regression phase IMO

So I guess this post is half rant and half anyone else have a similar experience/got a magic wand.

Is he getting enough calories in the day @GooglingFather?

My DF was advised to stop thinking of daytime food as 3 meals and 2 snacks and to start giving 6 smallish meals. So think of things like porridge & banana for breakfast, cheese on toast mid morning with some quartered cherry tomatoes and a tuna sandwich for lunch, that sort of thing.

Her DD went from not sleeping to sleeping through almost immediately.
