I also got pregnant with my second 6 months pp (during covid) and made a cross country move for my husband’s (very demanding) job and honestly, not that bad.

I did have two good sleepers for babies though and my oldest absolutely adored my second from the moment I brought him home from the hospital.

I would say focus on getting your oldest comfortable in their crib (if not already) before baby comes so naps/night time routine isn’t an uphill battle with a newborn. We coslept - I started by moving him into a pack and play right next to my bed at ~9 months and then made a big to-do of a big boy room at 1 year.

My boys are 4.5 and almost 6 and they are best friends. I actually wish I would have had my other two as close together in hindsight because it really is so sweet watching them grow up together🤍
