Hello ladies, I am new to this forum..

I gave birth to my first baby a little over 6 weeks ago, he took us over 3 years to conceive! We are incredibly happy we got to have this baby but my heart is still aching for another. I was told a long time ago I most likely wouldn't be able to have children naturally, so as you can imagine, our little boy came as a sweet surprise!
I always wanted 2 or 3 kids, and I don't want our LO to be an only child.. Call me crazy, but I'm ready to go again! Everyone says after birth you are incredibly fertile, I want to use that haha my fear is another 3 years or more trying... my biggest is fear is never having another..
Is it silly to start trying again so soon? I really don't know what to do.. I don't want my heart to take over my brain and end up making the wrong decision. What would you do? Can anyone offer some words of wisdom....
