He is also 10.5mo KookyK and is interesting to hear what you are doing, as I had been seriously considering the 2 shorter naps thing, because that happened by accident a couple of weeks ago and he STTN afterwards!
But I've hesitated, as he does like a longer nap & I thought it was necessary to have one that is restorative in the day, but maybe it's worth a go, just as a bridging thing for a bit!?
Today has already been a bit of a disaster - 2 tiny car catnaps, so will be a v early BT here - which always spells trouble.... and probably lots of NWs!
Hope you have a decent night with your LSN little one! Aren't they fun?!
