My 9 month old cries a lot when things are taken away from her - like her toys or anything she is interested in. Is this normal. Any ideas on how I can get her to stop throwing "tantrums"

At 9 months old, your baby is still in the early stages of development, and their ability to regulate emotions and handle frustration is limited. It is normal for babies to cry or become upset when things are taken away from them, as they are still learning about object permanence and developing their emotional skills.
