I’m having REALLY BAD baby fever and I need advice.

So recently my sister has had a baby and my brother’s girlfriend all around the same time. I have also been around my aunt who has an older baby (not one years old yet) and I really want a baby. I have 8 siblings, many little cousins, and my older sibling’s babies so I’m experienced with kids of many ages. Kids are a HUGE responsibility but even that isn’t changing my mind. I want to pounce on my boyfriend and yada yada but I know we are both not ready. I need help on how I get the idea of having a baby out of my head.
