Baby #1 actions when you became pregnant with baby #2

Jennifer

So my first born is now 5 years old and she has been really clingy here lately. When I move she is right behind me, when I go to sleep she lays her head on my stomach or on my chest. If I get out of bed in the middle of the night she pops up and comes to find me, but I haven’t told her she is going to be a big sister yet. Anyone else experiencing this with their first child?
