LO #1 turns 2 August 31, which also happens to be my due date for LO #2.

We were planning to start LO#1 in preschool when he turned 2, which begins the first week of September. We are only going to send him for 2 half days a week, but I am a SAHM so LO is with me 99% of the time, which means preschool will be a completely new experience for him.

I am just super concerned that getting a baby sibling at the exact time he will be starting preschool is going to be too much on him. I don't want to to turn his entire world upside down. Am I over-thinking this or is it a legit worry?
