BF, I'm probably not much help here, since C didn't have a proper nap routine until he went to nursery, at 9 months! Before that he just slept when he wanted, usually on me, or in the buggy or the car seat.
If it helps, when he started nursery he napped around 10.30am, then about 1ish, then 3.30ish. Once they had him in his routine (which seemed to take no time at all) he loved his naps! Even now it's dropped down to one per day, but he still loves it.
