I have 19mo old twin girls. Recently we have been noticing a change in their behavior to each other. They are jealous to each other about getting our attention. Whenever we are near, they fight with each other. They are also behaving very stubbornly. If they ask for something and they don't get, they become too much cranky. Being first time parent, we are little concerned, that, these behaviors do not become permanent. We are also clueless how to deal with the situation and pacify them.
Appreciate any help.
