DS is five weeks old and so far has been a pretty good sleeper. He settles on his own and generally wakes twice for feeding between 9pm and 7am and goes straight back down. Until now he's been sleeping during the day in a cot downstairs and slept happily for much of the day.
I realise he needs less daytime sleep as he gets older but for the past few days he's been resisting any daytime sleep at all. He has been awake since 9am and has been in his cot for the last 45 mins happily looking around him but not showing any signs of sleep. Occasionally his eyes start to close but he fights to keep them open. This is the third failed attempt at getting him to nap so far today. Yesterday he ended up really overtired and had a melt down late afternoon which is unlike him.
Any tips on getting him to nap during the day or is this a phase that will pass?
