They treat them like property rather than like people, make comments about how happy they are that their boobs are now bigger, care more about how expensive and trendy the pushchair is then about the baby in it, etc. I ran across a conversation one between one young mother and her friend. The young mother was out shopping, using the trendy pushchair to haul her bags. The friend asked where the baby was and the mother said she couldn't be bothered to bring it out, so left it at home, and freely admitted that there was no one at home to watch it.
