Just that really.
DS is 19 months old and has 1-2 hours at lunchtime, and 10-12 at night.
But it varies wildly! Last month he was sleeping for a good 2 hours at lunchtime and then 7-7. We had 4-6 weeks of that (this stands out because it was after 18 months of sleep all being a bit hit & miss, so it was lovely! And we thought we'd cracked it). This month, he is still getting a good lunchtime nap, but not going to sleep in the evening, even when bedtime is a bit later, then waking through the night (every couple of hours some nights, agh!), but managing to go through until a sensible 7am-ish. He's definitely tired by lunchtime.
AIBU to expect 1-2 hours at lunchtime and then 7-7? Happy to alter my expectations and routines accordingly if I am! I know they are all different but I'd be interested to hear what others a similar age are up to, sleep-wise.
