ive got smaller age gaps and after 2nd and 3rd were born i made sure my kids were the first and only visitors
we also made sure to make a massive fuss over them in hosp so they never felt pushed aside
Jhett wasnt too fussed when i was in hosp after having tahtah he loved her but was like oh yeah- the jealously was big at home but we made 100% clear only DH and i were to deal with his jealously and it didnt last and we made lots of Jhett only time (when she was sleeping)

when i had hudson Jhett wanted to take him home straight away (didnt care about me lol) but we really havent had much issue from both with jealously,
we just try to involve both kids as much as possible
