I have a daycare family who is pregnant . How I found out was through a disagrement and she told me because she was mad.

A few days later I asked her what her plans where once she will be taking maternity leave. If she would be keeping her son in my daycare or taking him out because she will be on maternity leave. She said "I want to keep him in".

I am not sure if i trust that she will really keep him in and was wondering if making a contract about staying through maternity leave for her would be a good idea to make sure she sticks to her word and then if she does not sign it find someone else?

What are your thoughts and ideas I need some good advice.

Thank you kindly.
