My daughter and daughter in law both used the same Valco baby bouncer - so 4 children have used the same bouncer. I believe it was used when it came to our family. My grandchildren, despite being 1 and 3 years old, continue to play with the bouncy chair either with their dolls or with each other playing baby. So a VERY DURABLE and fun product. Many dinners were spent quietly because a child was being bounced gently in the VALCO bouncy chair at the dinner table.
