I want to tell you what I want to tell my friends who have kids in that difficult 1-2 year age, that it WILL get better. Because it does. But I know better than to say that because it's so not helpful at this present time. But, sometimes when you're drowning in a sea of dirty diapers and grubby hands and toys everywhere, it's hard to remember that there IS life after babyhood!
Anyway, I think having a maternal instinct can possibly be genetic but I think it's also largely influenced by how you were raised, how you view kids in general and how comfortable you are with them. I'm the third oldest of eleven kids and I like to say that I've done everything regarding raising a child except physically birthing one. So motherhood is something that I know I will be reasonably equipped to handle when the time comes. But there was a couple years where I was so burned out on childcare that I didn't want to have my own kids for a very long while. I've found that as our youngest has gotten older, though, I've started to miss having babies around. Thankfully our church has a lot of new moms who keep me supplied with my needed fix of chubby cheeks and dimples. Now that I've had some time to think it over, I'm pretty sure I'll end up having kids as soon as I get married. Whenever that blessed day may come. Can't say I'll have 11, but a couple would be nice!
