Thank you for the tips on flying with kids! My daughter is so worried about the baby being fussy and bothering other people. I'll definitely pass those along to her. I've noticed that the steps don't register on my Fitbit when I'm pushing a grocery car too, so that makes sense! I'll have to put it somewhere else where it will track, or make sure I take my husband with me so he can either wear the Fitbit or push the stroller!
