DS is 11weeks old and just won't seem to settle anywhere other than in my or DH arms. Once asleep we do try to put him down in his Moses basket but within minutes he's awake and squirming round. We've tried leaving him to try and self settle but he just ends up screaming so more often than not he gets picked up again. This happens both during the day and through the night. Do we need to keep persevering or does it not matter so much at this point and we still have time to get him in a routine a little later on.
