10 week old not eating properly?

[HaveIGotPoosForYou]

I am a little bit worried about my little girl.

She is sleeping ALL the time at the moment.
She's chewing everything, generally quite happy but not eating very much at each feeding (2 or 3oz when usually has 5 or 6oz).
Feeds on the breast but it's a bit more uncomfortable now, feels like she's trying to clamp on me.
She's sleeping a helluva lot and isn't eating that much at all it's making me pretty worried.
Does anyone know if this is normal (10 weeks)?

If it is, do you know why it's happening?
If it isn't, what could it be and what should I do?

I think I'd be worried too. Although if she's happy that's a good sign. Has she got lots of wet/dirty nappies? Have you spoken to your GP or health visitor? Is she putting on weight?

Hopefully someone more knowledgeable will come along x

How do you know she's taking only 2 oz? Feeding can speed up massively as they get older.....

However the sleeping thing is worrying - I would deffo take her to a GP for a once-over to make sure she isn't coming down with a bug or sth.

I am presuming so as she's always gone on the boob but doesn't seem to get enough out of the boob as previously she used to always still be really hungry 15 minutes later; but she is getting older so maybe she's latching better and getting more, I'm not sure.

Thanks for the advice glad I'm not just going mad and worrying stupidly. I'd rather I was though, obviously.
