How do you know you're done?

Hi IM'S

How do you know when your done?

My story goes like this sorry it ended up being a long post.

I was blessed with two beautiful adorable girls 9 months and 3. If born at the same time they would have looked just like twins. I have been wanting a bigger house for years now so i have just returned back to work full time to get my dream. My husband wants another baby but his reasons behind it are not the greatest he more then kind of wants a boy. Don't get me wrong he would love a girl and he is the best father ever but his heart wants a boy.

I thought i was fully done returned to work life moves on i will get my new house in a few months. But for some reason i have a small feeling inside that secretly wants a third to. The only problem is i can't afford to get childcare for 3 kids, i won't be able to get my bigger house (the biggest dream I've had for years and years) it would go on hold yet again. I don't know if i could cope with three personally. Right now we have great family support who take our girls if we want to go out, to look after while I'm at work ect. We would need bigger cars, we cant afford it ect.

How do you know when your done? I think the only reason is we make gorgeous babies who are so happy, they go to everyone, they smile, they play together.

We have the most perfect life they love each other so much. I thought i was done, I'm happy to be done, life is great my dreams are coming true BUT there is one piece of me that just wants it. Argh anyone else feel like this? How do I get over it and be 10000 times happy and leave it at that?
