So my 3 year old loved going outside all the time but the last week or so he really just won't go out. He has a massive tantrum, won't have his shoes on, screams no and runs away. It used to be when it was raining but now it's all the time. He doesn't even want to go out into the garden. We've tried giving him choices with things like what shoes, which car shall we go in, shall we do this or this? Nothing seems to be working and I just don't get what's wrong?
