DH's job gave him a generous gift certificate for our DD's birth. It is valid at a mall and the mall only has one store that sells baby gear. I think we have everything we need as far as gear goes, so I'm thinking about buying a second Stokke Tripp Trapp chair (the gift certificate would cover a bit more than half of the cost). We have one for DS already. He is three, so we could probably put him in a regular chair in a few more months and let DD have the Tripp Trapp. But then again, I imagine he could probably still use the Tripp Trapp for years to come. Is it overkill to have two?
