Talk to me about 2 under 2

I just found out that I am pregnant this morning and I have a one year-old. She and her sibling will be about 21 months apart and I’m a bit nervous about what this looks like in terms of attachment parenting. We still breast-feed totally on demand bed share etc… talk to me about what this COULD look like or what it has looked like for you? Could use some reassurance lol
