The other thing I often have to remind myself is that your DS is still only a baby too. Keep your expectations of them realistic because it is easy to forget how little they are when they seem so grown up!
Sorry for the novel! Best of luck...
This ^^^^^^^ is so true.
My oldest two are 22months apart and yep it is hard but you do find a rhythm and how to make it work for you.
I was guilty of expecting more from my toddler then was reasonable as he seemed so much older than a newborn, but as the pp mentioned they are still only babies themselves.
Also, you will find second time round you know what is worth worrying about and what is not.
Good luck, you will do a great job.
