This picture reminds me of when my boys were little. They had lots of wooden toys & especially a locomotive with carriages that could be linked together to form long trains. They were a little bigger, sturdier & were in colourless varnished wood. Anyway, you had to be rather creative to get them to eat, at times. This would have worked fine. To pretend a train comes loaded & we’ll have to eat in order to be able to tow more.
