Hi Sorka! I posted a thread about the 1-2 nap dilemma a couple of months ago- you might find some advice in there too. My baby is a girl and she stopped to one nap just shy of 12 months (I think! I can't even remember now!) but was showing signs at 10 months. The transition took a while in terms of dealing with an over tired baby who was not tired to go to sleep before it was too late in the afternoon but we gradually be tended her go-down time fro. About 9:30-10am to 11-11:30. I'd like to put her down later again, just after lunch but at the moment she's well tired by 11 so we'll see.
