5 months, 2 weeks, a few more days - Evening stroll

Many evenings we all go strolling together; when Baba rides his bike to work, sometimes Augie and I walk to meet him on his way home at night. We use an outward-facing carrier when we don't want him to sleep, so that he can smell the flowers, see the sights, and kick around. But it's possible that maybe he's outgrown the Baby K'tan - what do you think?
