Terrible twos? Pssssh

Corrina โ€ข Mummy to a 3 year old little girl, expecting our second little girl in November '15. ๐ŸŽ€
So it seems my daughter, who was 3 in June, completely skipped the 'terrible twos' and has full force with being a 'threenager' anyone else's?! ๐Ÿ˜‘ about 70% of the time she doesn't listen or do what she's told, she cries (literally screams like a baby) when she doesn't get her own way, won't share with other children, she's started this thing where she runs away when we're out. I'm trying to raise a well behaved little girl but it seems impossible when she just doesn't listen ๐Ÿ˜ข she's very polite, knows to say please & thank you, but acts like such a spoilt brat.. I'm dreading her baby sister being born in November ๐Ÿ˜ถ๐Ÿ˜ถ
