Need opinions.....

We are going to a wedding tomorrow, and I have a sitter for both girls....sounds nice? But I'm nervous, our baby is almost 4 weeks old, and has been nursing around the clock and has now started nursing very well on my right side(she was only nursing on left just a day ago)!!!!!! I feel like she is really in a growth spurt.....

So.........I know it's good to get out once in a while, but should I really leave her with a sitter when she's doing so amazing nursing? (she also takes bottles just fine) We planned to go to the wedding with the baby...go home and nurse before bed and then go to the reception/dance without baby....her "normal" night routine is to nurse before bed around nine and then wakes up at midnight to nurse...then it's up in the air from there....So she would basically get two to three bottles at the most
