DS is nearly 7 months and the past few days has been a nightmare - not sure if it's teething or not - he already has two teeth at the bottom and I can't yet see any teeth coming out at the top. He's been crying much more than normal and also squirming around a lot. Have tried calpol couple of times a day and that seemed to help a bit. But today and yesterday I didn't give any calpol and he's been sleeping for England! He normally has 30 mins at around 9am and then 1-1/2hours from 12 noon. But the past couple of days he's slept for an hour in the morning and then not gone to sleep again till around one or two pm and then has slept for much longer - today he went to sleep at one and is still asleep at 2.30! Is this normal? It hasn't seemed to change his night sleeping habits - still sleeps the same hours at night.
