My 18 month old dd has just started having the most horrendous tantrums. Sometimes it's because she's tired or hungry so I obviously address that. However a lot of time it's because she doesn't get her own way. It starts off bad and turns into a complete meltdown for hours. I've tried everything from calming her down to giving her something to distract however that doesn't work. Anyway my mum told me to put her in her cot to let her calm down and realise who's boss. Do you think that's the way to go? For instance she's currently having a meltdown because I wouldn't let her climb down the stairs. I'm pulling my hair out now as to what to do.
