we went though this with DS1, but I had forgotten all about it. DS2 is 26 months and really needs to drop his nap but is too tired to stay awake. So we either try to keep him awake and he drops off at about 5pm or we give him a nap and he is awake until 10pm. Like tonight when I went up again and he had taken his bed, pyjamas and nappy off and was singing at the top of his voice. The rest of the household is fast asleep! It will pass, but FFS it's a PITA [bugrin]
