Yeah same here. Won't get dressed or brush his teeth or have a bath, it's a constant battle to get him to do any of it and most of it ends in a tantrum because we've had to force him. I've heard the 3s were hard but I didn't quite expect this level
It’s so hard but it is developmentally normal. When I feel frustrated (my little boy loves the word no too) I try to remind myself of that. The best thing you can do is be firm with your boundary but stay calm (on the outside at least). I lose my cool sometimes and always find that his behaviour is worse when I do. Whereas if I manage to stay calm then I can usually talk him round more successfully.
Right here with you! Genuinely done trying to tell him off I just ignore him now seems to be improving xx
