I've got a little girl who is 14 weeks old.
We had the hang of feeding for a while, but lately it seems to have gone downhill.

She'll latch (mostly right, but nipples are a bit sore again ) and suck for a little while and then scream. Then latch and scream. It's starting to become a rarity when she'll latch and feed without the hysterics.
It's very upsetting and frustrating. Sometimes even when she see's the boob she just screams at me.

Another thing that concerns me is her weight.
Birth - 3585g
1wk - 3560g
2wk - 3760g
4wk - 4220g
6wk - 4460g
13wk - 4850g

She put on just under 400g in 7 weeks. I know its better than none, but it seems so little.

She poops 2-3 times a week. Is exclusively breastfeed on demand. She sleeps longer stretches at night and seems to feed better. During the day it can range from 1hr to 4hrs.

I just dont know whats going on. I'm admist an interstate move as well, so I dont know if that could have any bearing on anything.

Any advice would be most appreciated, please.
