To stay home with sick kids

[talksensetome]

I am supposed to be going on a weekend away to meet my new boyfriends family this weekend. He has bought the rail tickets (not cheap).

Yesterday DD (almost 9) got sent home from school and was vomiting on and off last night. She was sick last about 10pm, went to bed at 12 and woke up this morning saying she no longer felt sick but had a bit of a headache, probably dehydrated.

DS2 (four) started complaining of ear ache last night about 4pm, had some Calpol and fell asleep, woke up about 8ish crying with pain, had lots of cuddles, more Calpol and perked up, was eating CoCo pops at 11.30 and then went to bed. He woke up this morning and said his ear was still hurting, more calpol and my sister said he has eaten his breakfast and is playing with his tablet.

DS1 (eleven) left for school this morningbut returned 20 mins later saying he had been sick on the way. He has gone up to his room in the loft and I doubt we will see him again at all until he is recovered. he tends to hibernate when ill.

My sister is at home with the children whilst I am in work today, she says they are fine and I should still go away for the weekend as her and her partner can manage fine.

AIBU to stay home anyway meaning my partner looses a fair amount of money on the tickets?

It is a lot to leave three sick children with my sister. But they are not that sick which is why I am wavering. I think mostly it is the four year old being in pain and wanting me when I wouldn't be there that is making me reluctant to go.

Surely I should stay home.

No, go. Your sister has said they'll be fine, you think they will be fine. It will be fine.

Also what if we go and I get sick or pass the bug onto his family/people on the train!
