DD2 loves her (.)(.) and i have never had a problem with her refusing to feed, even when she's teething she might be a litlte fussy but not to the point of NOT feeding.

Last night she was a little off, wouldn't feed kept biting my nipple and laughing about it, i put her in her bed thinking she was over tired maybe she would just go to sleep.. left her for about 5min nope sooking to herself so i got her out, THEN she toko the boob and fell asleep.

This morning she woke at 6 i got up, bought her to bed and went to offer her the boob she refused, i have been trying on and off since then and NOTHING, she wont take it.
She does feel a little warm and she's been chewing everything but she got 4 teeth in a week last week and i didn't have any issues.

Could it be teething, could it be something else i should watch out for?

I have put her to bed now, will see what she does and offer again when she wakes, i might try and express a little and if she wont take it will see if i can offer it to her in a cup or something.
It's been probably 12hrs since her last BF... should i be worried?
She had toast this morning and seemed to eat ok but has been a little cuddly.

Hope she's not getting sick.. it's so unlike her to NOT want the boob.
