Safety Check Please. 6.5 months, sidecar crib

I will be moving the nightstand out of the way. How does this look for a 6.5 month old who wants to roll and sleep on his tummy? We’ve been bedsharing since 4 months old but just adding the sidecar tonight. All tips and ideas welcome. The adult mattress is secured in place. Are the towels shoved between mattresses safe?
