When we get home from work, we keep the babies in their car seats and just strap them into the stroller and go for a walk. We do this in hopes it'll put them to sleep because we're having a problem with this time of day. Most of the time, they're asleep when I pick them up from day care. But then they wake up when we get home, so their nap is interrupted and they're fussy because they're still tired but they start to fight sleep. Sometimes the walk works and sometimes it doesn't. But at least we're outside and getting a little exercise.
