For the first 3 months our eat play sleep was a little bit over the place, she wanted to comfort feed alot and sometimes have short naps othertimes have long naps. Wasn't really til 3.5 month mark that we fell into a real eat, play, sleep routine.
I'd say just to demand feed, if bubs wants it, it will also help build up a good supply.
I found the easiest thing to do in the first few months was just go with the flow of what Ashleigh wanted and did whatever worked for her to keep her settled.
