Hi! My DD was the same when she was younger. Loved the sling (we have a HAB) but hated the pram. We also have the beema Q and the bassinette attachment which she hated unless she was sound asleep...one day we just layed her flat in the pram without the attachment and she was fine. It really wasn't until she was old enough to sit upright in the pram (2 months is probably a bit young for him) that she started to like it. Now I have absolutely no problems. If your DS has reflux that probably wouldn't help. The harness still isn't tight enough on my DD and she is now 6 and a half months old...they are just big straps! Good luck..keep persisting..maybe try without the bassinette, otherwise have hope that he will outgrow this and come to like being in the pram.
