Would it be selfish of me to take daily walks with my 2 year old and 5 week old in the stroller? If I bundle them up and make sure they are covered well -- I could even drape a blanket over the 5 week old to cover him completely (cover the carrier with a blanket) and bundle up my 2 year old with a coat and mittens and hat?

Today is supposed to get up to 50's, I figure I can take them during the heat of the day, but it's getting quite a bit cooler pretty quickly around here and I really want to get into a habit of a daily walk.

Anyone else take little ones out with them for daily walks?

Oh yes! I always figured if they were warmly dressed and it wasn't windy ... they'd fine. I bet your 2 y o will love it!
If it gets to be freezing weather, you might consider carrying the wee one in a bundle on your chest, under your coat.

Selfish? Not at all! All babies should be so fortunate to have Mommies who do that!!! As long as they are well bundled up it will probably be good for them!!!

My little ones (twins) are 21 now so I don't do it anymore.LOL But when they were little I would bundle them up in the stroller and walk all over the neighborhood. They loved it. I think the cool air energized them. I miss those days.
