1/ Take care of the "before", the moment of the announcement
Simplicity is sometimes the best solution to announce the big news! We will avoid formulations that are too reassuring "don't worry, mom and dad will always love you", "don't worry, everything will be fine" that could ultimately distress the child. If the child does not feel any particular anxiety, one should avoid apologizing or reassuring him/her excessively. Involving the child during the pregnancy is preferable in order to involve him/her little by little and at his/her own pace.
● During pregnancy, take advantage of quiet time to explain to the older child what a baby really is and how it works. He sleeps a lot, eats a lot, cries regularly and that is OK. For you it is, but it can be frustrating for an older child who doesn't understand why his new sibling doesn't want to play with him. Books will be your biggest help to deal with all this, as well as picture books! You can also, why not, take a tour of the room with him/her to introduce the important places for baby and their functions: the bassinet, the changing table, the bath, the bouncer.
● Prepare baby for the birth by explaining how it will happen to avoid D-day anxiety. Explain then that you will have a bit of a tummy ache, that daddy will take you to the maternity ward to get the baby out of the tummy, that a nice doctor will help you welcome the baby and that you will need to rest for a few days. During this time, explain to your older child that he or she will be looked after by grandma or grandpa, an aunt, a sister, a brother or a relative - and that daddy will be back very soon.
● Before the birth, offer your elder to choose a small gift for the new baby. A way to gently involve him in his new role as "big". You can also make him a present to celebrate the arrival of the new baby! The arrival of a child is a celebration for the whole family, so you might as well make the most of it (you can imagine the new baby spoiling his brother or sister). You can also offer to choose the baby's blanket or his first outfit!
