In about five minutes, Isla will turn four and two minutes later, Grace will too. This is both extraordinary and mundane in equal measure. I am staggered by how quickly the last four years have gone, yet it seems entirely right that we are here. These grown up girls who have no toddler in them at all, have school places ready, have ambitions and plans, well of course they are now four, of course they are.

Isla is bossy in the loveliest way. She is always the mum when they play games or the teacher or the doctor. She loves Grace unconditionally, knows that she is the older sister, knows that she should somehow look out for her. She can sign most of the alphabet, knows the letters of her name, loves to count and she knows some basic Spanish (thanks to Dora). She likes unicorns and ballet, thinks that her daddy is an actual superhero, and prefers dresses over jeans. She thinks that when we go one stop on the train we are in London. She can’t say small but tells me that things are ridiculous. She loves peas and strawberries and hands me tomatoes uneaten with a grimace if I dare put them on her plate. She is a wonderful little girl who loves me to the seaside (not far) but her twin to the moon.

Grace is hilarious. She is emotionally younger and physically albeit briefly. She is smaller than Isla but ever so slightly taller, a testament to her little birth weight probably. She loves on people, will touch your cheek and ask how you are, will haul herself onto your lap and wedge herself in. She still loves her dummy beyond measure and it probably makes me a terrible parent but it makes her happier than anything else and she’s little for just a blink of an eye so I don’t really care. She loves dinosaurs, knows their complicated names and pronounced them correctly, knows a kompsognathus from a plesiosaur and will roll her eyes if you tease her and get it wrong. She isn’t a tomboy, she just likes dinosaurs and I will defy anyone to tell her otherwise. She wakes up early no matter when she goes to bed. She doesn’t like cereal very much but loves croissants and grapes. She potty trained herself when she decided she was ready, we were just along for the ride. That’s Grace, feisty and funny and completely herself. She currently wants to be a dentist and put plasters on baddies. I don’t correct her. She can think whatever she likes for as long as she likes.

Being their mother has been the greatest challenge of my life. Yet it has been the greatest privilege too. An honour. I sometimes simply can’t believe that they are mine, that I grew them in my body. I’m grateful too to the baby who is still not here, as because she is coming, because we get to do this again, I can just embrace the fact that they are getting older, growing and changing and becoming their own people. I think I’d be a wreck if it wasn’t for that.

So Happy Birthday to my beautiful daughters. I love you both further than the seaside!
