DS2 is 15 weeks and I'm having real difficulty with his daytime naps. At night he's pretty good - goes down at 6.30-7, has one feed in the night and is then up again around 7am. In the day it's a different matter. He gets really tired after a maximum 2 hours awake (and sometimes as little as an hour), but he won't sleep for more than 20 minutes, after which he thrashes about and cries. He doesn't want to be awake - his eyes are shut and he makes his tired cries,but he can't settle himself back to proper sleep? At the moment I'm either going in and out of the room every 2 minutes to give him his dummy or stroke his head etc. or leaving him screaming, but neither of those are easy (particularly the first as I have a 2.9DS1 as well who needs attention and creates all sorts of havoc if I leave him alone). DH does shifts and is often sleeping in the next room, so I can't just leave him to cry himself back to proper sleep (and DS1 still has a lunchtime nap 4 or 5 days a week, which doesn't happen if DS2 is screaming as he hears him).
This is probably completely incoherent but what can I do to help DS2 have the sleep he wants and needs? DS1 was much easier and slept for an hour in the morning and 2 hours at lunch without a peep by this age (at least i think he did), but I shouldn't be comparing them anyway...
Any tips on what to do to help DS2 would be much appreciated, anyway. Thanks
