Knowing when to stop!

So i am now 6weeks pp but when i found out i was pregnant i desparetly wanted a girl we already have a 10yr old amazing boy and i dreamed of cooking, horses etc to share with a daughter. It didn't happen and i can honestly say i ADORE the son we have he is a gem and just so amazing.

That being said i have already been bit by baby fever. BUT we were pushing it with 2 money is tight and though we make it work its a struggle at times. So 2 is our limit and it definitely brings me to tears some days. I'm not sure if its just hormones or a stupid dream that won't die. Anyone have some words of wisdom or gone through something similar?
