Hi hun. I can't believe Miss A is nearly 3 months already!! The girls have given you lots of tips/advice and I think it's a tired thing because she is sounding exactly like H when he is being fussy at the breast when he's tired.
I would give ABA a call hun. They have been absolutley brilliant when I've called and have truely saved me a few times. Give them a call hun and see what they say or your LC if she would make you more comfortable.
