Babysitter Needed for my Children

We have an event to attend this evening and are looking for someone to care for our infant son throughout the evening when he wakes for bottles/ comforted back to sleep. We would be gone by 6 p.m. and return at the latest by 3 a.m. My elderly parents live in the home but cannot handle the weight of frequent wake ups but they can care for my older daughter and her needs/ put her to bed so no need to worry. We have 2 dogs who are friendly but a little annoying lol but they would be kept behind a gate with my mother. We would provide dinner/ snacks & fresh sheets in our room where baby would be and you would be free to relax and watch TV/ nap etc.
