I heard baby sleep inside yaolan will be difficult switching to sleep on bed. But some baby just can sleep on yaolan instead of bed.
My baby start sleep yaolan at 4 months. Now 10 months still sleep yaolan. Afternoon nap with yaolan, night sleep on bed.
My baby sleep yao lan since 1 month. I let her sleep during the day and co sleep at night. No issue so far 15 month.
My baby takes nap in yaolan since 3rd or 4th mth because he had flat head. Night time he will slp in bed.
I only use it for naps
It's absolutely fine(:
Is ok
