I can't really comment on Evelyn not walking as my daughter is 16months and still not walking (not for my lack of trying, she just not interested) but she does have an insane vocabulary, better than most 2year olds so I'm a big believer in them all developing at their own rate etc. But she doesn't appear to talk much either, having those ridiculous headbands over her ears all the time probably doesn't help! And I wish she would.just let her explore and get messy, it makes me so sad.
Her latest story about Cassie being goals, yeah she does look amazing for having a 6 week old baby but that's probably because she didnt gorge herself like an enormous glutton while she was pregnant like you did Kate! The pictures of her pregnant make me feel sick, she looked like a balloon about to burst any second making her enormous face even bigger! Grim.
