My child is still not walking at 13 months old. Should i bring him for a check?

This article says that some kids walk at 17 or 18 months. http://www.babycentre.co.uk/a5170/your-13-month-olds-development If your baby is able to stand sturdily and attempts to walk, there should be no need to worry. Doesn't hurt to ask your PD though.
