"Celebrity buggies
The recent crop of celebrity babies has one thing in common: they travel in the Bugaboo Frog.
However, it wasn’t popular with our users. It’s a four-wheeled pushchair that comes with both a carrycot and pushchair seat and is a pricey £500.
Its chassis adjusts for use in town and on rough tracks, snow and sand, and the seat can face forwards or backwards. The Frog is easy to push but our parents found it tricky to fold and, although there was an excellent instruction DVD, our ergonomist rated the user manual as the poorest on test. Handling, especially on kerbs, was awkward, too, and the under-seat bag was small and hard to reach. The Frog is a bit small and the seat might look snug after baby’s second birthday."
