sahm blues

Sebrina
So I guess I'm just needing some encouragement here 🎣 lol..
My best friend of many years and I are in two different chapters of life. As we go along we are leading more and more different lives from each other. She visited today and informed me she is trying for a baby. I was so excited! I have a little one so I immediately think oh yay maybe you'll join the mommy club with me. She goes on to say that since I so graciously offered to keep her kids while she worked she'd like to get my hair done for me from time to time... now I don't remember ever saying I would nanny her child for free!! 😭 she says over and over I just can't see me staying home I have to work I have to feel like I'm doing something with my life, I just need to feel productive, and even remarked she can't see her not contributing to her family. 
Now I'm in a funk. 😒 
She knows I'm a stay at home mom. Maybe it's my hormones (?) but I'm feeling for one thing, insulted that she obviously thinks I do nothing at all. For another that she sees raising your child as not contributing, which may be why she expects me to do it for free? Which brings me to the last, I'm so stressed that apparently there has been a misunderstanding somewhere and she thinks I want to keep her potential child every day without compensation 😫 I told her I don't feel like I can make any promises that far in advance so please don't count on me for something like that. I'd be willing to baby sit some, hell I want to, but I just don't want to be free labor 😕
So I guess the question(s) I'm posing here are. What would you do in my shoes to smooth things over as easily as possible? And also, as working moms, is this how y'all feel about sahm's? 🙁 I swear I'm not a lazy person. 
Oh and also, apparently she doesn't like my hair 😂😅
