Finances

What is a good amount to have put away for emergencies? We also have a 8 month old son who has a savings account. Just trying to budget how much is usually in an emergency, savings, and now our sons account. We are getting our own place, and now since my husband is not in the military I’m just anxious because we are now responsible for rent. Both of us have a stable job. But you know, things happen. I just want to make sure that if something happens it won’t hit us hard. Especially with our son.
