The Honest Company Boy's Organic Cotton Short Sleeve T-Shirt Multi-Pack Baby and Toddler Set

Is it hard to get over baby's head?

What's the size difference between 24 months and 2T?

Wont the raw edges fray overtime? Seems to me they'd shorten the lifespan of the shirts.

Can anyone compare these to a 2t size in carter's (after washing and drying)? are they about the same, smaller, etc? thanks!
