Tell them to fuck off... well actually, tell them nothing, ignore completely.
When I had DS, everyone was around, even in the hospital, I had so many visitors that I wasn't told in advance about or prepared for...
When I got home it was worse, people in my house every single fucking second of the day. People I hadn't seen in months, or years.
I had a bad tear, was trying to breastfeed, was a young first time Mum and just wanted to be on my own with my baby.
As it turned out, they were contacting my DC father who said 'It's fine, come round!!!'
And I did explode. Big time! There was a group of about 8 people one evening in my kitchen when DS was just about 2 weeks old, I was hiding upstairs in pain and trying to feed. I
'd had enough, they were in my house and making noise, I stormed downstairs and told every last one of them to get the fuck out of my house or they would never see my or my baby again, told DC dad to get the fuck out with them as well if he had a problem with it.
We do what we have to do to get by in those first few weeks, these visitors just ruined that time for me. Their want to see your baby does not trump your need to be a new mother. Ignore all the texts and put your boundaries down.
