I like the age gap too! Especially when #1 can dress, feed, toilet herself!
BTW Saram, my #1 just asked re. your ticker, and thought your "baby" looked very beautiful.

Sliding #2 into #1's routine is definitely the way to go.
Ruby #2 just gets woken up all the time as she is in/out of car etc. But she has learnt v.v. quickly to powernap wherever, whenever!!
