I have an only just 4 year old, -the baby is nearly 1 and starting to crawl etc.
My older child is trying things like stepping on the baby's hand, or shouting at them, or physically stopping them doing things in quite a rough way which sometimes is effectively pushing the baby over and therefore banging their head on the floor.
Now I'm not worried for the baby's safety but so far we are dealing with by expressing surprise and concern for the baby, and going to help and suggesting (but not enforcing) they need to repair things. But there are clearly either some big feelings flying around, or just experimentation perhaps? I've been hanging tight so far.
How would you deal with this?
