And I thought that women's clothing sizes were bad

Baby clothing sizes are completely random and totally vary based on which store those clothes come from. Lily still fits into some 0-3 months clothes. However, she mostly wears 3-6 month clothes but on occasion, she fits into some 6 month clothes. She has steadily been gaining weight over the past month (thanks to the milk-making drug Domperidone) so I think that she'll more consistently in six month clothes. Needless to say, it's always a fun challenge trying to figure out what to dress her in!
