We seem to have turned a corner with the sleeping here too. Thursday night was bit better, Fri and Sat not great but not as bad as before and he was in a travel cot and getting picked up everytime he squeaked so he didn't wake everyone up (staying with friends fri and all of us in same room in hotel on Sat), then last night he was better again. Waking at 12 and 5 then going back to sleep himself until 7.15. Fingers crossed it'll keep improving and we won't go backwards again.
Main difference last night was him settling himself after being fed. he always used to do this fine but had been a pita recently. Then at weekend it got to the point where when he was picked up he stopped instantly and then cried again instantly when put down. So we said right we're going to have to fight this battle when we get home as its getting silly- but then last night he behaved.
Ended up in our bed on Saturday, we all only went to bed at 11pm so was desperatly trying to not disturb ds1. In some ways I can see why people co-sleep, he sucked and I dozed on and off from 6-8am. But I only had about 3 inches of bed and couldn't change position as I would have fallen out of bed. Meanwhile ds1 was sleeping in a double bed all on his own! Didn't seem fair!
Had good weekend in Liverpool at cousin's wedding, it all went really well and it was good to stay out late even though ds1 has been throwing tantrums ever since as he's so over tired. The drive home yest wasn't too bad either. Went to The Beatles museum in the morning which ds1 really enjoyed.
I was quite proud of myself and ds2. Apart from his milk we didn't take any food for him at all. He ate everything we ate including roast lamb at the wedding meal. And it was so much easier and more relaxing to just put food in front of him while we ate our meal. And the lamb kept him occupied for hours!
