Go ahead, we already have two

My daughter was two when we had conceived the other baby. She reached three years old half a month after the new baby's arrival. She wasn't very enthusiastic about it because it is a boy. She wanted a baby sis to play with. At just three to her a little brother is a disappointment, kinda of. She did try to kiss the baby a couple of times and even to give him a bottle. Now she pretty much ignores him because she is much 'bigger' and he is only a little baby. She looks down at  her 'baby' brother because he couldn't talk or walk. She'll turn four soon and to her view the baby will stay as baby forever, never up to the par of her level.
