My DD is almost 3. She has always been energetic but not wild in her play. Since the arrival of her brother 8 weeks ago she is getting progressively worse. Tantrums numerous times a day. Throwing toys. Weeing all over the floor when previously dry. Shouting and generally being a nightmare. I realise this is normal to some extent due to new baby. However she is getting worse. I have tried ignoring her tantrums. However she just gets more manic which causes the baby to wake up and start crying which in turn upsets her even more. Any tips as I am at the end of my tether and am starting to dislike her.
