Savings

Not sure where to post this- but how much money should I have away in savings before having a baby? I married at 19 and am now 20. Major baby fever and I make quite a bit of money for someone my age but my husband is starting college 3rd year in the fall.
How much money should we have in savings before we have a child? Or any other advice. 
I am trying to be smart while this baby fever is killing me.
