Hello. Childish jealousy in a child is often caused by the fear of losing the love of parents. Therefore, older children can sometimes openly demonstrate a negative attitude towards the baby. It is important for you to choose the right behavior strategy so that your daughter does not feel lonely. Talk to her, pay attention to her interests, hobbies.
WITHolder children are often jealous of younger ones when they feel they are superfluous. In addition, children with a large age difference have no common interests. Moreover, any requests from the mother for help with the little ones are often perceived as a burden. In the future, they will compete for the attention of parents and compete in achievements.
Chances are good that children with such a difference in age will never be especially close. In order for this not to happen, it is very important to constantly emphasize that the eldest child is very important, needed and loved.
It will be great if it turns out to gently “include” the eldest daughter in taking care of the youngest child and constantly to focus on the fact that it is already quite large and does a very important and necessary work, helps mum and dad.
At the same time, it is important that with the advent of a new family member, the firstborn, like the “big” one, will have not only new responsibilities, but also new rights. Think about what “you can’t, you’re still small” can be transferred to the category “you’re already big - it means you can now” - this will affect the older person’s self-perception and allow her not to regress into infancy, which often happens to older children after the appearance to the light of the younger ones.

Here, of course, you need to learn more about the difference in age and how children manifest their jealousy, because often this is only an experience and a feeling of guilt of the parents themselves. All the best!
