My cousin & I live together and raise our kiddos together. I have a 6 year old son & a 3 year old daughter. She has a a 3 year old & 7 year old boys.
Just provide nighttime snacks, possibly dinner. Then bedtime. The 3 year old girl is still potty training so take her to the toilet every 45 mins.
In a gated community. We work overnight so we need an overnight sitter.
