Bottle refusing 7 month old on nursing strike

[123456kent]

Feeling very stressed. My 7 month old is crying and crying when I try and breastfeed her. She’s always cried if I try and bottle feed (7months of attempted combi feeding with no success) but today and yesterday she has now gone off the boob completely and is a very grouchy baby.
I can see a white tip on her lower gum and it looks inflamed, that might explain things.
I don’t want to give up breastfeeding for a month or so, as we have a 2 week holiday coming up and for ease I want her to still be breast fed.
She slept through the night for the first time this week, and then this has now happened, and sleep, naps and feeds have gone to sh*t!
One consolation is her food intake is good and her diet is good so I’m not concerned about nutrition for now - just sleep, mood, and my supply (I haven’t pumped yet).
She’s breast fed once today, reluctantly. Offered multiple times. Gone to bed without any milk.
I’m getting very irritable and stressed...
OH doesn’t understand the issue, just thinks she isn’t hungry.
Any advice/stories/hand holds?

Hmm I have bottle fed my 2 at that age so no advice about breastfeeding as such. DD2 went off all feeds twice. Once was because she had bronchiolitis and the other time was due to thrush. I think you need to take her to the GP in the morning for a check up. Less than 1/2 the usual feeds in a child under 1 is a concern.
You could try a dream feed tonight or maybe try some Calpol and see if she will feed an hour after that in case it is pain that is stopping her. Hope that's helpful x

Thank you. I have tried to dream feed her already tonight but no interest (I dream fed her for 6.5 months so it’s something she is very familiar with doing) and we gave her Calpol before bed.
Other than being grouchy cos she’s hungry she does seem well though, no temperature and had very very happy moments today. Also eating food well. But yes, if she still doesn’t feed overnight or tomorrow I will seek medical help. Thanks.
