I now know all the words to Frozen!

Jamie Crawford, 40, is a business owner and lives in Lisburn, Northern ireland, with his wife frances, 32, a civil servant. They have four daughters, ella, eight, faye, six, Juliet, three, and Cora, seven months.

JAMIE SAYS: At the gym I’m teased for only producing girls. But I laugh along because I genuinely couldn’t be happier to be a dad of daughters. I don’t feel less of a man because I don’t have a son, although I know that attitude still exists.

At work, customers are always asking me when Frances and I are going to try for a boy. They can’t believe our family is complete without one.

Since Ella was born I’ve been on a steep learning curve in all things female. Sometimes I can’t believe the things I know — like how you only put conditioner on the ends of your hair to stop it getting greasy, and which outfits go on what dolls.

Quite often, after dropping the older girls at school, I’ll find myself singing along to their Frozen CD, forgetting it’s just me in the car. I know all the words! I can be in and out of the bathroom in ten minutes flat, and as the girls become teenagers I suspect I’ll be allowed even less time.

I don’t want to turn into an overprotective dad, but I know the world can be a dangerous place, especially for young women — so I’m planning to teach them all self-defence.

I was actually relieved when we found out we were having a fourth girl last year. A boy would have been smothered by three big sisters, it just wouldn’t have been fair. We’ve no plans to try for a fifth, our family is definitely complete.

WIFE FRANCES SAYS: With each pregnancy all I cared about was that the baby was healthy — not its gender. But by the time Cora came along we’d decided to find out early what we were having, because I couldn’t bear the incessant ‘ you must be hoping for a boy’ comments.

The only downside is that because they like the same toys and TV shows, there’s a tendency to lump them together. I have to remind myself to give them
