Jamie has gone down in his cot for one of his naps every day. Its been a proper sleep as well instead of 15 mins. I suspect he may also go down for the other one buts it nice to snuggle up in bed with him and I only have two weeks of that left
His also been a bit better at night. We're normally getting at least one four hour block and at least one (and sometimes more) longer blocks.
Taking him out of his sleeping bag and him walking round the furniture seems to have made a massive difference. Just hoping it lasts!
