Re: 14 month old eating manners
I think eating at the table helps. If nothing else you are paying more attention and can catch it before the mess gets out of hand. Some amount of mess is to be expected at this age, they don't really get that they aren't supposed to and I think it's good for them to be comfortable and relaxed with mealtimes. But if they are throwing/playing more than eating I do like the pp suggested and ask if he is done. Whatever his answer if the playing continues I take the food away and say all done.
I don't have dogs so I can't really speak to that, but D's babysitter had dogs and I'm pretty sure most of his lunch went to them everyday so I suppose it's pretty normal to give the dogs food if they are around.
