She has been clingy and saying Mommy all the time! Oh my! It sometimes drives me crazy!!
According to BabyCenter:
How your toddler’s growing: Your baby is growing up fast these days, walking, talking a little, and probably even using a spoon or fork when she eats. Every game she plays, whether it’s pointing to different body parts when you ask her to or putting objects into containers and taking them out again, teaches her about the world around her. One of the things she’s learning is that she’s an autonomous entity, not just an extension of you. How can you tell if your child has grasped this concept? Watch her in front of a mirror; if she recognizes herself and isn’t trying to reach out and touch the “other” baby, she gets it.
How your life is changing:
The way your child interacts with the world around her will tell you a lot about her temperament — how she’s likely to respond to different situations, people, places, and things. For example, some children are flexible and adapt easily to change, others need a more predictable schedule. You can modify your child’s environment to help her succeed. She’s depending on you to make her feel comfortable. By respecting her needs, you can help her develop to her fullest potential.
