My dd is almost 1 and has always been a messy eater, we do BLW so expect a mess (and get one lol)

her latest habit is to throw her food, she always used to drop some things over the edge of the highchair but now she full on pitches stuff everywhere. I know it's a sign of being finished as well as I guess just an experiment, but should we be trying to curtail this or is she too young to stop a behaviour. She will continue eating if stuff is put back on her tray so I don't want to finish the meal as soon as she does this as she is small anyway and not a massive eater.

We try and eat most meals at the table with her, at least 1 or two a day anyway, to model normal table manners. At the moment we say 'no' in a firm voice when she does it and take what's left on the tray away until she stops then give some stuff back.

What have other people done? I don't want to make a big deal of it but I'm not sure if I should be just leaving it or starting to get on too of it now.
