I just want to say something.

When I had DD1 I was insistant that I only wanted DH in with me while I was in labour. My mum & MIL came up after I'd been in labour for 10 hours & were going to sit in the waiting room.
They asked someone how long they thought I'd have & they said a while. So Mum & MIL offered to come in just while DH goes out for a smoke - he did really well going so long! He only had the one in 18 hours!
Any way I told the midwife that I wanted them out as soon as DH came back.

But as soon as they came in I changed my mind. Mum had gone through labour 3 times & MIL 6 times. They knew what to do & how to help.
They knew what the MW & OB were talking about.
If MIL wasn't in there I could've been taken up for a c/s. They were talking about it coz it was taking so long & she suggested they give me a bit more time. I'm glad she did.

We were both young & didn't go to any pre natal classes though. Things might be completely different for you.

I wish my mum was there for both the other 2, but she couldn't be.

You don't have to, but maybe your mum or someone to help you through the labour & make it clear that as soon as baby comes out she is to go & give you & your partner time.

I don't know you, but I don't think I could've done it with out my mum.
