One of the reasons we love the Stokke Tripp Trapp high chair was because it doesn't have a tray; the kid sits right at the table and eats and plays along with the family. It's a dynamic that works well for us, but there are definitely folks who prefer to give a kid a little space of his own. Unfortunately for them, Stokke doesn't offer a tray for the Tripp Trapp, but with 35+ years of Tripp Trapps in the dining rooms of Europe, a few companies have stepped in with aftermarket options.
DT reader Melanie has been keeping me up-to-date on their tryout of the translucent plastic Play Tray from the Danish company, 4mykid. Her verdict: it's "worth every kroner." [Though to be clear, those kroners and euros are probably feeling a bit cheaper to someone spending their newly powerful Candian Dollars.]
For folks stuck with American money, EUR54 - VAT +shipping might seem a little steep. But I seem to remember a wooden tray that used to turn up on eBay.de for like EUR5-10, a big crescent-shaped thing cut from a sheet of matching birch plywood. Didn't have the handy spill-containing lip of the Play Tray, but what do you want for five euros? Aha, there it is, the Clic Clac Tisch fur Stokke Tripp Trapp. Sehr schoen.
