Jonty is the exact opposite of Flynn in his sleep patterns. He started sleeping through at about 3 weeks and never looked back, never woke with teething and has always slept a solid 12 hours at night. You could even transfer him from the car to bed and he would stay asleep or if he woke, would just go straight back to sleep.
Jonty is still having day sleeps, about 2-3 hrs a day if we are at home, and until recently he was still sleeping 12 hours at night. Just recently I have noticed that if he has a big day sleep, he is not wanting to go to bed until about 9pm. So we are in the process of cutting day sleeps down to every second day. Sometimes this doesn't work and Jonty falls asleep wherever he is during the day.
The reason why I think Jonty has always successfully put himself to sleep is (a) he sucks on his finger and (b) his blankie, which goes absolutely everywhere with him. (a whole other post). :)
Sweet dreams little boy.
