I really think she projected her anxieties onto them right from the start, and it’s actually had an effect on them. On an early vlog when they were a few weeks old she said she would even use the white noise machine right next to them when changing their nappies “so they wouldn't cry”. I think she seen them crying as her being a bad parent in her silly brain, whereas babies cry, sometimes for no reason, it’s just babies using and finding their voices. Since then every time they’ve made a louder noise it seems they’ve learnt that’s a big no no, so I think they are now much more quieter than they actually should be. Just my imo.
