What is it with parents that never pick their kids up? Sure, if you take your kid out of the stroller s/he might want to run around a little bit. You're at the zoo! - it's where kids run around.
Anyway, it's ok to touch your kids, pick them up, hug them. They're not designed to live their first few years in a car seat/stroller.
