Naps for 10 month old

[Laur89]

Hey all, looking for some advice for naps for my 10 month old please! He usually wakes for the day between 6.30 and 7.00, then will nap at 9 for about 45/50 mins, then until recently he would nap again from 1-3ish. Then bed would be at 7. However the past week or so, the afternoon nap seems to be getting more of a struggle, he will sleep from 1-2 then won't go back down again, no matter how hard I try. This makes late afternoon tricky because he's so tired! My question is, how many hours of day sleep should he be getting at his age? He sleeps 11/12 hours at night straight through, it's just his naps I need some help with! Thank you x

At 10 months I was doing:-

6:30-7: wakes
9:30-11: nap 1
2:30-4: nap 2
7:30: bedtime

So 3 hours daytime sleep then generally slept 11 hours at night.

I'd be aiming for 15h sleep in 24h. It comes from the 234 schedule for 2- nap days:
2h between waking and first nap
3h between two naps
4h from second nap to bedtime.
That gives you 9h of awake time through the day. So 15h of sleep. That might be 12h overnight and 3h daytime. Or 11h overnight and 4h daytime, and so on.

DD1 dropped to 1 nap a day at 10 months - she would sleep 11-1.30 each day
