This is definitely a winner for my baby boy Charles. He is 4 months and has been using it as a teether, as well as free play on the mat. It will grow with him as he learns to stack them. One very versatile toy to have for months, if not years.
Love that this is 5 teething toys in one! Little Miss loves holding on to the bigger rings at 3 months and Mr 3 enjoys stacking his and using each ring to make a different pattern in playdough.
