I don't allow it. I use to but I found it so hard to run my day. My little ones would cry for their mom and my older one was crying it's unfair her mom gets to play here all day or all morning but my mom doesn't. Everyone acts differently around someone new and my schedule goes out the window. They can transition before the start date. So they come to the park with us one morning. Easy when we're out of the house. Then next day they come in to play for 20/30mins tops then they leave I find it way easier on the child to without mom hanging around.
