How many kids do you have? and do you want more?

I have 2 kids, 7 year old daughter and 7 1/2 mth old son, I thought I was done, but recently I get this feeling when I see a pregnant lady or even a women with a newborn, I keep thinking I want that again, I know my son is only 7 mths and he is still young, it just goes so fast, and ive also told myself, there is no point in having another just for the pregnancy stage and newborn stage it is gone so quick, I really thought after having my second I wouldn't feel that sensation when I see pregnant ladies again, I thought id be well past it. im only 24, so I guess in the future I could have more, I definitely want to be done having kids by 30, I just wonder if even if I did later have one, if the same feelings would come back anyways. Whats your situation? How many? and do you want/plan on more? thanks
