Occasional sitter for a 6 and 2 years old - Full-time / Part-time

Hi we are an average middle class family. Dad, mom, son, daughter, and puppy. We are a young family that needs assistance on occasion. Our son is a clever chatter box. Our daughter is a mischievous friendly toddler. We all have old souls and most people love that about us. Our parenting is pretty basic. We Discipline and spoil our children equally. They are pretty self sufficient. Especially if they are in their own home environment. Which should make them very easy to watch. We just need someone we can call on nights we need to get away from the kids. Depending on life this could be a once a week or once a month thing. We know the summer is approaching and that’s when we typically need assistance the most because of all the birthdays and family occasions that are not kid friendly. On those nights we will prep the kids with dinner and for bed and need someone to fill in until we get home. The return time could fall between 10pm - 3am. We are are flexible too. We stay in the wicker park area. We don’t mind bringing the kids to you but if the kids are comfortable being at home, we would prefer that option. We don’t have any set schedule. We typically may just have plans for the weekends on certain occasions.
