DD just turned 1 and has started to get REALLY upset when she doesn't get her way. yesterday she cried for 10 blocks (20 min) because i wouldn't let her hold my cell phone. she's not allowed to hold my phone ever, she reached for it, i said "no, not safe" and the crying ensued. i alternated between holding her and pushing her in the stroller the whole way home. she cried on and off the whole time. i verbalized about how mad she must be "happiest toddler on the block" style, but it seemed like every time i used my voice she got more upset. any thoughts? this is just one example of her sadness about not getting her way that have happened in the past week or so.
how can i set the stage with consistent boundaries, but also not have her get so frustrated?
