Help!!!! My son is 6 and a half months old and has never slept more than half an hour for his naps (except for 3 occasions which seemed completely random ie the conditions were no different to normal)This applies to sleep in his cot, the buggy and the car. He sleeps pretty well at night now, going to bed awake and sleeping from 7pm to 5 ish and occasionally 6am. Going to bed later doesnt seem to help him sleep later but he usually cries at 5am whereas at 6am he chats happily upon waking.He starts to get tired an hour and a half after waking and if I recognise it in time will go to sleep without too much crying. If I try to put him to bed any later, he is often overtired and we have a real struggle.A bit of controlled crying has got us this far, but I dont know what to do about extending his naps. At the moment I have to get him at least 4 naps to get through the day without him getting very cranky. It's all i can think about and is beginning to stop me from going out to swimming/yoga classes etc with him because I cant seem to fit in his meals and naps around any kind of activities. I would love him to have at least one long sleep(one and a half hours perhaps?) so at I could have a bit of time to myself. Any tips????????????/
