I am no expert but I just wanted to offer some HUGS and to say given that your LO is only 7 weeks only there is a good chance you are doing nothing wrong
Just things that might matter....
Do you breastfeed or formula feed? Is there a reason you are doing 4 hour feeds?
- at 7 weeks many babies are still on a 3 hour feed schedule with cluster/ dream feeds. Is there a possibility that he is hungry?
If he does nap how does he fall asleep? on you? lying down in a crib? with motion?
Does he have a pacifier/ is he swaddled? Is he okay upright but not lying down?
- I know my DS settled much easier with a paci and swaddle (later dealing with props was not so fun but I think with some reflux issues the sucking can help)
- I havent dealt with reflux but there is some great info on this site... just an example

Good Luck
