My DS will sleep from 7.30pm - 7am. Then has daytime naps from 9-10.30am, 12-1.30pm and then around an hour 3-4pm, maybe more. Then sometimes he even has an extra 30 mins around 6pm. This adds up to around 16 hours sleeping.
When he's awake he's very active - a real wriggler! And is very bright and alert.
Is this normal?! Most of my friends have babies who only have 2 daytime naps of around 30 mins - an hour.
