Thanx guys. I am pretty sure it is the reflux coz she'll feed well but fidgety for 3 to 4 mins then pull off arching back and screaming, poor love. Not sure whether its worth insisting but this is what has worked last few feeds: When she pulls off shh hher and and calm her, rub back etc and talk quietly to her trying to coax back on boob, and she will about 3 times so all in all shes probably latched on for 5 mins but suck is pretty weak at this point, mostly coz shes very tired after the whole ordeal but has NEVER fallen asleep on boob so pulls off irritated and rubbing eyes and wants to go to her bed.
I am thrilled as she finally eat her solids for lunch! AND she then took subsequent BFs very well...maybe shes learning how to feed in order to not be in pain?
i have also tried to offer boob every 2 hrs due to short feeds and she will actually latch on

she never used to come near boob before 4 hrs!
What do you think? step backwards?
