Paint me a picture of 3 m/o baby life

Expecting FTM here. I am trying to decide if I want to stay home or go back to work part time (3 hrs/day).

If I go back, it would be when LO is 3.5 months.

Can you paint me a picture of what life may be like then? I’m struggling with how abstract & unfamiliar this is.

What will LO be doing? How rested & healed might I feel? Should I be thinking about pumping at work? What have I not thought of?

I’m lucky that finances aren’t an issue & I have an awesome job. For sentimental reasons part of me would like to stay on 1 more yr to see some things through.

TIA!
