Thanks girls for putting my mind at ease re tummy time! Actually yesterday (just after I posted the question) he lifted his head up during tummytime; just wanted to make mummy worry first.... Prama, I will try the sofa trick today; much easier than crawling around on the floor trying to get at Jasper's eye level!

Ania/Jacki - Jasper has been fighting sleep for the last few weeks. We do have a routine which involves putting him in sleeping bag, closing the curtains and wrapping him (one arm out). But most of the time he works himself up into a big hysterical cry; I have been trying to get him to sleep without getting him out of his cot/bassinet by patting/stroking his tummy and singing a lullaby until he stops crying (this can take up to 15 minutes). Sometimes I have to do this more than once before he falls asleep.
Lucky; this week he seems to be getting better at falling asleep and doesn't cry for more than 5 minutes, so hopefully he is learning how to self settle... He is asleep now after only 5 minutes of grizzling, so hopefully it was just a phase he went through... After his midnight feed he falls asleep quite quickly without much crying. I have to say, it is so hard on you when they are obviously unhappy, but I am happy I persevered with getting him to sleep in his cot.
