DS is 4 months and isnt a great sleeper, he generally has 3 naps a day, but they only last between 15 mins and 45mins, usually 30 mins. V occasionally he will do an epic 3 hour one if started off in the buggy, but only v rarley. When he does have good long naps, he sleeps for longer at night, well the first stint anyway, which is usually from 7 - anywhere betwen 10 and 1, then he is awake every 2-3 hours for a bf. Any tips for getting him to nap for longer? or should i just not worry about it?
