It's my mum's birthday in a couple of weeks and my sister has booked a table for a meal out.
She text me to say that she had booked the table at so and so restaurant at so and so time, could we come?
I reply to say that DD, who is 1, and I can come but OH can't as he is working.
She replies saying that she is concerned about me bringing DD as it will be busy and I won't enjoy myself and she's not sure about the crowd in the restaurant 
My reply is simply: I don't have childcare, I either bring her or I don't come.
I'm so pissed off. I live a way away from my parents and her, so it's a trek for me to get there. I don't have access to childcare in the same way that she does. I'm horrified that she would suggest that I don't bring DD when that essentially rules out me coming? ? And she knows this!
I know it sounds petty but it's really irritated me! AiBU to tell her to shove it?
