my little boy goes to bed around 6.30-7.00pm and sleeps til aound 7am (usually wakes up once at around 5-6am but goes back to sleep easily if you put his dummy back in). He has always had a nap of around 30-45 mins at 9-930ish but for the last couple of days he has taken around half an hour to settle then only slept for around 20 minutes which makes me think he is ready to drop this sleep. his next nap is usually after lunch -12-12.30ish, for anything from 1-2 hours, will he last until this sleep or do I let him have a later morning nap before lunch and move the time for his second nap?
