She is 9 weeks old. This has started in last week. Instead of cooing and thinking she is 'beautiful' and cute as others keep saying I just keep thinking critically, her hair is coming out a bit, her tongue comes out too far after tongue tie snip, she looks scrawny and not like a cherubic chubby baby, she doesnt smile enough. I'm also doing it to DS 5 - his mouth looks gummy (teeth coming out) he's too thin. I dont say it outloud its just running through my head. What the hell is wrong with me????? I have a history of PND with both other children (I have three). Is this the start of it?
