Older mums

Hi there I'm 6 weeks along with my 3rd child. Due 3rd Jan. I'll be 39 when babba arrives. I have a 16 yr old and a 13yr old from a previous marriage. This will be me and my partner of 10 yrs first child together and we are very excited. I'm also pretty nervous being an older mum and having to learn it all over again. Are there any more older mums out there?
