Welcome!

Routines will fall into place in time and help put order to your days. Just like it took you time to adjust to your paying job,same holds true for being home. Some days will be smooth and others difficult but so were your days out at work.
Does your 3 year old attend preschool?

That could be a good time to spend with just the younger one. Look into the local library. They have kids' storytimes and a good place to find other at home parents there with kids to offer support or to just talk.

Good luck.
