A 2yo toddler being sleep trained via cry it out at 3 months. Independent play 98% time, limited parental interaction. Toddler has things taken off them quite abruptly, no explanation given, if they're not meant to have the items, e.g. open felt tip pen accidentally in reach etc. Any resulting tantrums just ignored, no explanation by parent/ attempt to console/distract/divert.
Toddler pushes/shoves other toddlers off toys they want to play with. Toddler will take toys away from other toddlers even if they have shown no interest in them. Toddler tantrums are extreme but short...
I think it could be the first paragraph causing the second? I.e. unintentional taught behaviour...toddler has things taken away abruptly, so it's OK to do it to others?
