Ride along boards are the perfect solution if you are expecting a second baby and do not want a double buggy. They give the ability for your first child to stand or sit behind your pram on a buggy board if they are too tired to walk or struggle to keep up. It is the perfect solution if your first child is at an age where they are starting to not use a stroller any longer and starting to walk.
Some pushchairs have their own specific buggy board or you can get universal ones such as the Lascal Buggy Board. These will fit 99% of pushchairs.
*Please note using a universal buggy board will affect your warranty guarantee on your pushchair
