Taking baby out

Kim • Pregnant with #1 after about a year of trying. Due end of October and very excited!
How old was your LO when you first took him or her out and about? My baby is 3 and a half weeks old, one month on the 23rd. I'm going stir crazy being in the house all the time. Husband and I have taken her on a few walks around the neighborhood, but I'm ready for more. Is it still too early? I don't want to be selfish and take baby out just because I want to stay busy if it's too soon to be safe for her. I should mention she was 5 weeks early and spent a week in nicu. She's totally fine and a strong, healthy baby now.
