9 month old sleeps badly then screams all day!

[kmt500]

Help! My 9 month old has never been a great sleeper and regularly wakes up several times a night, usually getting fed back to sleep. Recently he's become incredibly cranky during the day and spends much of the time screaming at the top of his lungs with nothing I can think of to settle him. We are pretty sure he's tired as on the rare occasion he sleeps well (which for us means waking maybe 2 times a night instead of 5-6) he is like a different child the next day.

We have previously tried shh-pat and pick up put down without much success and I don't want to do controlled crying. We co-slept when he was little and would happily do this again but he doesn't seem to want to be in the bed with us and sleeps even worse! However the lack of sleep coupled with the stressful days are wearing me down..... Any suggestions please?!?

How are his naps during the day?

He usually has 3 naps a day lasting about 40 mins - haven't figured out how to extend these, but he goes down no problem in his cot.

They'll probably get longer in time. And when is his bedtime?

Goes down to sleep about 6.45, again no problems, gets put down awake and doesn't require fed to sleep. Usually the fun starts about 10.30-11 and continues every 1.5-2hrs from there....

Try adding a layer to his clothing, cotton not fleece.
