When I have difficult times with them and I'm getting really frustrated I have realised that it's usually me :( I'm trying to rush them, or I'm not paying enough attention, I'm busy cleaning the kitchen or something, I'm not listening to what they're really saying. So I'm trying to work on that. Just slowing down and letting them experience life without rushing them through it because I've got stuff that needs to be done. Really, it can wait! I will only get this time once. If they want to help with the washing it might take twice as long but they are learning and having fun so I just need to chill, lol.
So I don't really have any useful advice yet because mine are only little but looking forward to what everyone else has to say!
