Quoting ~*My heart is complete*~:" I'm so nervous! We've been dating a little over a month and his mom lives out of town, so this weekend ... [snip!] ... man around and 2 because I really don't want her to think I pass my kid off all the time. Any tips for meeting the parents??"
Personally, a month into a new relationship, my kid wouldn't know the new guy and neither would the parents. Actually, I wouldn't bother to meet the parents until I was more stable in the relationship. That is just me.
For you, do what makes you feel comfortable. If that means leaving your child with your mom or a sitter until you get to know his parents better, so be it. Just be yourself.
