Can you take a t-shirt or sleeveless undershirt and sew some toweling to the front and slip it over his head?

And here's a tutorial.

You could also make a regular bib with long ties and double tie the bow. I do this with my sneakers.

The adult bibs for seniors have 2 of the metal snaps in the back of the neck.

Looks like a tight snap (or 2 snaps) would work better than velcro. Or a smock-type bib with velcro all the way down the back. Looks like sleeves would help too. Found these websites with discussions on the topic:

Edit: Note there is a caution about making bibs too hard to remove, as they can then become a strangling hazard. Probably not as much of a problem for a 3-year-old, though; more of an issue for babies.

I have made a few with snaps, which are easy to apply to the bib. Instructions are on the packet of the tool you need to purchase but are quite reasonably priced at places like Walmart. But I also agree with the individual suggesting a bib with sleeves. Though these are bigger and more work.

Measure neck opening and then divide opening in quarters with pins. Cut ribbing 2/3 the neck measurement for snug fit a little bigger if going over the head is a problem. Sew ribbing into a tube or circle. Fold in half. I think I used to make the ribbing 2" wide. Divide ribbing into quarters with pins. Match pins on neck opening pin in place right sides together. Sewing with bib side up, sew ribbing to bib stretching ribbing to fit bib. Clear as mud I bet. Email me if you have further questions. Not hard at all once you do it.

It may be that having something right up at the neck is bothering the child. You might try a bib that is a bit looser at the neck by having the back with 2 crossover straps rather than hooking behind the neck (from the shoulder to under the arm at the opposite side). This would slip over the head. You might attach a bit of velcro where it connects on the sides to allow for growth or just make the straps a bit longer and let them out as the child grows..

How about some type of buckle up the back? Maybe a couple of them.

I have made bibs from towels for my handicapped brother. I took a bib pattern and used just the top portion of the pattern. Using denim and snaps for the top, I attached half of a bath towel to the end of the pattern. Since I doubled the pattern and sewed it together, it left an opening at the bottom of the pattern and I inserted the towel into the bottom and sewed the opening shut. If you want you can gather the towel to fit the opening or just use a towel the size of the opening. These wash like cast-iron.

To DSCH: By the way, if you go to the hardware store, you can find a much heavier-duty Velcro that you can put on equipment. It is wider and has more staying power. I think that one of the suggestions for use said that you could put it on the side of the house and attach hosing to it. This is the self sticking kind, but I thought of sewing it on something that I wanted to hang that had some weight to it. Never got around to making my project, but I still think that this would work for your needs, as it would be a lot harder to pull loose.

The adult bibs I make have a yoke attached to a hand towel. I use elastic on the yoke so it can be stretched and put over the head. It cannot be removed unless it is again stretched. It might be worth a try.
