Anyone with 4 or more children...?

I am a 26yr old mother of 4 gorgeous kiddies, a son 8yrs a daughter 4yrs another son 3yrs & another daughter 9months :) I love them so much & didn't plan on having anymore. Although when I was pregnant with my last daughter I got upset at the thought of it being my last pregnancy. Anyway for about 6weeks now I have been thinking about nothing else! I really think I want another baby, my head says no for practical reasons but my heart has other ideas!! Any advice?? Or anyone feeling the same??... No negative, boring comments off clueless people who do nothing but judge, not interested.
