Teigen also took to Instagram and shared a lengthy carousel post in which she talked about always wanting four children «for as long as I can remember» before offering insight into the family's plan for a fourth baby.«After losing Jack, I didn’t think I’d be able to carry any more babies on my own. To be honest, I’ve personally blocked out a lot of my mindset during that time, but one clear memory is being surrounded by people who wanted to make sure I wouldn’t go through that pain and loss again,» Teigen wrote.
