Hi. Welcome to BB.


At 6 weeks he could be having a growth spurt.
Try to keep a routine, but he won't really settle into it at this age. But it will help in the long run. Eg, bath before bed. He'll get to know that when it's bath time it's nearly bed & will get used to that.

Try putting him down awake if possible & getting him do go to sleep in his cot. If possible get him to put himself to sleep.

It's not easy at that age, but it will get easier.
Sleep when ever you can. Whenever he sleeps if possible. Good luck.
