It does not for us. My FIL doesn't really have much interest in the girls...hopefully things will improve when my LOS are older?
My MIL lives close by and she babysits occasionally but nothing regular! She did offer to watch LO 3 PT but I ended up resigning instead.
My brother and his fiancée just purchased a home very close to my parents. They are undecided about having kids but my SIL says she will not pay a cent for childcare if they ever have a child since she assumes my mom will be the nanny. Ha, I can't wait to see how that pans out!
