Question for moms with a toddler and a baby or still pregnant with baby #2

I’m currently pregnant with baby #2 and scared. I’m scared bc it’s already tough for me with my 3yo son. I had my son in a previous relationship. I am currently in a happy & healthy relationship and my man is sooo supportive and he knows how hard I struggled before he came in my life. But I’m still terrified thinking of how this baby will change my life. And how I’m now about to have to put my goals on hold once again.

How did baby #2 change your lives?

And what advice can you all give me to overcome this fear..?
