DS (22 wks) has for the 3rd morning on the trot stayed asleep when I put him on the sofa (all snuggled in), usually his first nap is on me after a feed.
His timing as great as we were going to go to a new baby group, so in that case would you wake him or let him sleep?
Incidentally I've chosen to let him sleep, first time mum so apologies if you're like wtf!! He is a cat napper so I dont expect him to be down for long...sigh...
p.s Tomorrow I will try the cot but I wont hold my breath
