I’m freaking out..

I’m 29 weeks pregnant and all of a sudden I am completely freaking out I have a 1 year old daughter and a 2 year old son and a newborn due really soon. How and I suppose to have 3 kids under 3 like I’m freaking out it’s starting to hit me that 3 little humans will be depending on me and needing me to care for all of them.. for moms out there with 3 under 3 please please give me some advice.

Also this will be my 3rd c section so I have to deal with recovering from that to.
