OK - thanks for that. Sounds good. We seem to have the same idea!
Today he woke at 6.30am, we had a puppet show to go to at 11am so I took lunch with me, he fell asleep at 12.10 in the car so I transferred him - he slept until 1.25, so that's a 1hr 20 min nap. As you say, once he gets used to having a nap around 12.00/12.30, perhaps he'll lengthen it (that would be mighty nice!) I still can't believe that he'd ever sleep as much as 2hrs - but you never know! That also should work well with picking Toby up from nursery too at 2.30 - so long as he's not going down any later than 12.30. For the longest time DS#1 would have his nap at 12.30, it wasn't until he got a bit older - probably 2.5 years old that we moved it to 12.45, then 1.00.
I think your suggestion of extending your outing in the morning, rather than risk him falling asleep in the car around 11.00/11.30. Lately I have been able to transfer him without much of a problem.
So far as total sleep goes, he's generally sleeping between 11 and 11.25 hrs at night and 1hr 15 in the daytime (at the moment!) I guess that's still in normal range. He's happy, and that's what counts!
Thanks! I'll let you know if we hit any hurdles and I need more advice.
