We’re expecting our 2nd when first one will be 3.5 years old. We want to use the newborn set again to have baby at the table while we eat and am wondering whether to buy a 2nd Tripp Trapp or put our first in a normal chair with booster if needed. Tempted to go for another Tripp Trapp as I like the 3 year old to have the ergonomic footrest rather than dangling feet but don’t know if it will be a waste of money. How long did your older kids use their Tripp Trapps for?
