[REIDmylips]

I'm sure it wont be any time soon but when should ds no longer be nappiung during the day? He is 19months.

Thanks

DD1 stopped regularly napping at about 2.6/7... at 4.4 still sometimes falls asleep in the car in the afternoon or on the sofa after nursery

Thankyou. I had absolutely no idea when it will/should be!
