My DS is 11 weeks old tomorrow and since about 5/6 weeks has been sleeping between 6-8 hours a night at once. Last night I put him in his cot for the first time as he’s outgrown his Moses basket and hammock (he’s still in my room) and he slept from 9:00-12:30 then woke up but put himself back to sleep at about 1:00, then he was up again at 2:00, had a quick feed, something he hasn’t done for weeks, and then back to sleep at 3:00, he half woke up at 4:15 but not fully and stayed unsettled (grunting, wriggling etc.) in his sleep until 5:30 when he woke up for good. Is this because of the cot? I’m so worried it will have messed up his sleep, he’s usually such a good sleeper and I don’t want to spoil that. Could he be having a growth spurt or going through a leap early? If anyone has been through something similar and can offer any advice on if/when he’ll go back to normal that would be great!
