Yes out in public is a bit different, but I don't really get looks anymore. Either coz they've stopped or I stopped paying attention. I don't go very far with DD1 now she's at school though, so people are a little surprised when I say I already have a child at school.
I do get people who see me & think this is my first or second coz I usually only have Bri with me or I'm alone. When they try to give advice about what I've got to look forward to I just say 'Yeah I've done it twice now, so I should be right'. I usually just get an 'oh', or 'well you're an expert then'.
