2 under 2

Hey mamas! I have a question for moms who have 2 under 2 already or have had 2 under 2! My daughter will be 16 months when baby boy is due at the end of March. She clearly doesn’t understand what it means for mom to have a baby and there is no way to explain that to her. My question is, what was your experience with when to introduce the baby? Did you wait until you got home, or did you bring them to the hospital? I’m so stressed about this! I have never been away from her like that and am a SAHM, so she is super attached to me. Just don’t know what is best or if it will be harder for her to see me and then have to go home. 😔
