I have this friend who has a younger sister that just had a baby. The sister is 19, so she's not a child, but she's still a young mom. I had a kid at her age, so I understand the struggles and the opinions of others hurting you. However, she posts stuff that makes me worry so much for her baby and I don't know if I should say something. Like mother to mother, as someone who has been in the situation? For instance, her son is 6 months old and she already has him forward facing in his car seat, which is so dangerous to me for a baby his size! And she lets him sleep in his crib, with a few blankets (like 3-4) and a pillow! I don't know if I should just ignore it because it's none of my business, or if I should offer her unsolitcited advice (which I hated!) as a friend. We're not close, but we are friendly towards each other. I just don't wanna cross any lines and make her feel like a bad mother, because she's not, she just worries me sometimes.
