Recommended baby bed or duyan for toddler

Hi Mommies! My baby is now 18mos. During day time sa duyan pa din po sya natutulog and he’s getting taller na po, medyo naiipit na kasi sya sa duyan but still sounds asleep naman. Do you have any suggestion/recos for duyan or baby bed or anything na pwedi nyang higaan na u think will make his sleep comfortable at hindi mainit?Naka fan lang kasi sya. And hindi sya sanay matulog sa bed without me dahil nasa work ako. So normally sa duyan pa rin sya natutulog.
