So she'll be 43/44 by the time the boys go to school. That is middle aged, there might even be grandparents younger than her at the school gates. She'll hate that she won't be the youngest, prettiest and thinnest. Unless of course she ups the cosmetic procedures etc..
My Mum was 27 when I went to school. When my Mum was Nikki's age I had left and was on my way to university. It'll be tough on her. I'm all for older Mums but I think Nikki will struggle. Especially as her own Mum will be ageing too. Hope she's still on the gram by then. It'll be comical
