I am pretty sure I am right, but just need a professional second opinion. my daughter is 22 months. and in the last 3-4 months she has become very "testing", in the past month uses the word NO very freely, and throws some tantrums. She also knows when to run to daddy when she doesn't get what she wants from mommy. I am assuming, with my experience with kids, this is somewhat if not completely normal, and I just need to stand my ground, but be patient and calm at the same time. On the other hand, she can be very sweet, she is very helpful and loves to "clean up", help with her baby brother who is 5 months, and has her good moments. Please, just some reassurance that she's not being "bad" (as my husband says) and that she will grow out of it with the right guidance.
