Am I being reallllly naive?!

Charlotte

I am due my 2nd baby in 3 weeks and I have a 25 month old. I feel like the baby will just “slot in” because our 1st is super chilled, independent and goes to nursery a few days a week. My partner is super hands on too. I just feel as though going from 1-2 will be easy for us, but am I being naive? Any tips?
