So I am a nanny for two kids (3yr old girl, 9 mos old boy) and I love them to death and I love my job and working with their mom and dad. I work in their home every day (except weekends unless they have a date night or something) and while yes they are my employers, I still feel that I have a great relationship with them and enjoy having coffee together and talking after my daily duties are done. And their mom has given me great ideas for wedding stuff and offered to help with designing my invites and such, and we often talk about wedding things.
Would it be weird for me to invite them? I would enjoy it if they came, but I'm not sure what kind of employer/employee etiquette/rules that would be breaching if any.
I would like to invite them, but I'm not sure how they would feel about coming...
Just looking for a little advice

Thanks in advance!
