The straps loosen pretty easily.

love the backpack! my son feels "like a big kid" carrying his own snacks and toys. its super cute watching him pack it up before we leave the house

I think it would be nice if these were more accessible in stores. I actually drove over 2 hours and came across these. I bought all of them except the brown one for my 3, 2, & 1 year old at the time after just giving birth. These have came in so handy! People compliment them all of the time saying how brilliant of an idea they are. They have sRead more about review stating Lifesaver! — I’m seriousaved my kids’ lives a lot! As soon as one got out of the car, I’d put it on & wouldn’t take it off until I was loading them back up. If I didn’t, they’d take off running into the road. I can’t tell you how many times they tried to as I’d get another kid in & out but again, luckily they had it on. I love that it doesn’t feel as if I’m walking a dog & my kids can carry their own things :D The only issues we have had was in the beginning they would all get tangled up with each but, again, there’s so many kids. The other issue is that they’ve learned to slide out of it somehow when they threw a fit. It would be nice if they were slightly bigger or had a better side pocket. Maybe 1/2 - 1 inch bigger. I wish they had a princess version and maybe they did in the past I’m not sure, but I ended up finding one in a different brand for the then newborn. After having these Diono versions, I found the other princess one to be horrible quality. I can’t brag enough about these Diono ones. I also can’t thank you all for saving the lives of my kids countless times had they actually been able to run into the street while getting another kid in and out of the car!!!
