Hi there,
Sounds like your DS is transitioning from 2-1 naps and probably needs a bit less daytime sleep.
At this stage you could try
- capping the morning nap to eg 30-45 mins, and poss pushing it a bit later (eg 30 mins). You may have to bring pm nap a bit earlier after shorter am nap; or
- pushing am nap out later, letting your DS sleep as long as wants, then doing pm catnap to make it to BT
With EWs, lots of people find the first of these options works best.
What do you think?
