For those STM and more, our DD who is 2 1/2 has started to act out since the birth of DD2 (who is 2 weeks old now). We have tried redirection, being more stern, timeouts, but it is starting to grate on our nerves. She has gone from being the sweetest/politest little angel to a full blown she-demon. Seriously, she is a totally different child, and DH and I do not know what to do. She has started to hit, kick, scream, cry/fit, attitude/stubbornness, refuses to eat most of the time, and spitting in my husbands face (tongue out blowing spit). She never did these things beforehand. The only thing she has improved on is her potty training, i.e. no poop accidents since birth of DD2. We really need advice. She loves the baby, always wants to hold and kiss her... but everything else has become a battle. Please help.
