Thanks for the advice.
I think he does have reflux as he is fussy at the breast and has started possetting more and more as the weeks go by. He has about 6 of the reflux signs so I'll bring it up with my Dr at my pp check up on thursday.

We cosleep atm so I cannot raise his mattress but will keep it in mind when we move him to his cot (whenever he decides to sleep longer than 2hr at a time).
