3 Under 3

So I just found out that I'm pregnant with my 3rd. Really early but still pregnant. I've always seen myself with 3 kids and we have been planning for a 3rd. We only tried once for this 3rd baby. Our first 2 took a couple of times before we became pregnant. So I guess I'm still in shock very excited and VERY nervous. I guess I never really thought I would have 3 kids under 3.

So my question to other moms that have 3 kids what I'm I in for? So people have said the 3rd was no change and others have said it turned their world upside down.

Looks like I'm going to be in the market for a car that can hold 3 carseats lol
