Baby #2 was born two weeks ago, and despite careful preparation, and lots of praise and positivity for helping and getting involved with her brother, dd has started displaying some difficult behaviours. For example spitting (purposefully, smiling when we tell her her behaviour is not acceptable), hitting, shouting, screaming 'no'... I know that having a second child is a massive change for her, and am trying so hard to be understanding of the psychological upheaval etc, but it is really hard to know whether we should be clamping down harder on these behaviours? I drew up a chart for her today to collect stickers for the absence of these behaviours, thinking that this positive approach might encourage her - but no joy. She is so wilful, and it is really upsetting to see her behave like this! Anyone got any experiences to share? I feel torn apart here - trying to be with newborn, husband going back to work next week, and dd behaving like this! thank you
