Kid savvy ?

I practically raised my little brother while my mums at work and my dad was studying abroad. But I have a confession to make: I don't 'get' children. Its not that I don't like them it's just that I have absolutely no idea what I'm meant to do with them. I mean they are cute, funny and them mumbling and falling over trying to walk. Ok. I get all that but once I'm with kids I feel like I'm the kid. And they know that I'm a total idiot, and they could be laughing at me.
After marriage, the next big question is always 'so when are we expecting grandchildren, nieces & nephews or god-children?' . For me it's just nerve wracking and I've managed to hide this terror successfully for many years. I always make sure I'm not alone with a child who might expect me to actually do something to entertain it. I'm too uptight to do silly faces or baby talk.
My husband and I ever since we started dating, he made it clear that he wants kids. I on the other hand agreed mainly because I trust him to be the one looking after the kids, disciplining them and so forth. But now that we are married and we have family and friends asking us when are we starting our family I somehow feel as though something's changed. It's no longer a fantasy it is a matter of time and I'm more scared by that prospect.
This has been made infinitely easier by the fact that my husband is amazing with kids. We would babysit our nephew and he is just amazing. I tried a few times to loosen up and join in the fun of entertaining him but what do I say to a kid? Especially one that is way smart for his age. My husband on the other hand knows exactly what they'll find funny and what they might want to do.
The other time I was left alone with our nephew while he is having his bath. My husband went to get his pajamas. As soon as my husband left we were both staring at the rubber ducks awkwardly.
Thankfully he already knew I'am no kid savvy. He find it amusing instead of being troubled.
Watching his friends have kids I do not envy their life style at all. I see mums pushing their strollers around town and all I can think of is tired-no-time-for-herself-kinda-mum. Or fat-messy-haired-mum.
One day I would actually want children, so I was starting to worry about locating my mother instinct. Guess it will come with age and how settled I'am with life.
For now I'm looking forward to babysitting my nephew time and time again. Because the last time I read to him in French and had a great time playing hide-and-seek accident free. But of course my husband was around to coach me.
