So frustrated - can't tell if DD is hungry or pacifying reflux pain!

DD definitely has reflux (on zantac, a bit better but still has issues). She tends to overeat and self-medicate when she is in pain - of course causing more reflux and a vicious cycle. DH is now convinced that any time she is hungry less than 2 hours since she last fed that she should not eat - even from the same breast. However, we're pretty close to 6 weeks and that infamous growth spurt! Today she has really been wanting to eat almost all of the time that she's awake. She's been fussy, but impossible to tell if it's from reflux or because she's really hungry! She is definitely rooting, etc. Any advice? I don't want to deny her if she really needs it but also don't want to make her reflux worse...
