My dd is nearly 4 and for the last 2 years has been incredibly challenging - pushing the boundaries, throwing tantrums all the time, being defiant, etc etc. sticker charts/punishments/rewards/time out etc etc all to no avail.Is this something she will grow out of or am I facing a nightmare teen from hell when she hits 13? Do all challenging toddlers (girls) turn into challenging teenagers (girls)? If so, can anyone recommend any useful strategies or good self help books on the subject?
