We tried it first with our Take n’ Toss sippy cups and it didn’t hold onto that sippy cup really well as my son quickly figured out how to slide it down as the cup is angled. We tried the strap with several toys and another brand of sippy cups that has handles though and it worked great! I really liked that it was quite short because it made it really easy for my 22 month old to be able to grab whatever he had tossed really easily, without even really needing to pull on the strap to get it. We tried the strap on both our car seat and our stroller and it was super easy to attached. I totally plan to use it connected to the high chair as well when my baby-to-be hits the throwing phase!
