My 5 month old is fascinated watching peoples drinks, especially if they have ice/fruit etc floating in them.
So I thought he might find it fun if I half filled a couple of small very sturdy jars with water and various floating/sinking objects to push around and look at on the soft floor of his playmat (while constantly supervised, lids taped down for extra paranoia even though I know he can't open them).
My DM saw and has basically had a go for my dangerous parenting - glass is a terribly bad idea and that the baby might suddenly learn to throw them.
I'm pretty sure I would struggle to break one by throwing, I know I've dropped one from counter height into a tiled floor and it didn't break, and the baby can't really throw at all (he can drop things, but I was only playing down on the floor on a soft mat where they had no where to fall). Plus I was right there helping him roll the jars.
My instinct is to ignore my DM (long history may be clouding my judgement) but the doubt is in my mind. So mumsnet jury, was I unreasonable to let my baby play like this?
