If your toddler wears two-piece pjs or one-piece footless pjs, but doesn't yet sleep with a blanket, do they wear socks to bed?

DS is 14 months, and doesn't wear two-piece pjs yet, but he has a couple of footless one-pieces, and we put socks on him overnight with those. He's almost outgrown the 18-month sizes, so I think we'll be moving to two-piece sets soon. Should I keep putting socks on him?
