How to prepare for a 4th?

[DontKillMeMrGhostFaceIWantToBeInTheSequel]

Had a... lovely surprise the other week to find out i am pregnant with a 4th child.

There will be 6 years between this baby (if all goes well of course) and my current youngest and I'm sure so much has changed.

We got rid of all the baby stuff when our youngest outgrew it so need to get all the stuff. I've downloaded the midwife app and got my appointment but even that was such a different process from last time.

I'm just feeling a little overwhelmed with it all and could use some advise on what essentials I need to get/think about.
