So we currently have an 18 month old and another DD on the way. New baby will be born in May when DD1 will be about 20 months. We are considering two options. Which do you think is the better option? Any experience or advice?

1. Keep DD1 in crib and buy another crib for DD2
2. Switch DD2 to a toddler bed and use original crib for DD2.

What do you think? TIA
