Sorry, not sorry rant

Call me bitchy, but this drives me insane. I was the first of all of my friends to become a mom and not a single one of them supported me except my best friend and I stopped talking to every one of them other than her. My son is 3 and a half now and since then several of them have had babies, but I'm still not super close to any of them. One of the only ones I talk to just had a baby girl three weeks ago. Her whole pregnancy she was coming to me for advice and questioning me about every single detail from day 1 to labor. I was really supportive and helped as much as possible. But the second her baby was born, she suddenly became an expert about everything and now she feels the need to try to tell me what I should be doing and trying to tell me all about being a parent. I'm in the last month of this pregnancy, and I really am about to snap on her. I'm sorry, but you do not turn into an expert over night.
