Socks for bed

So as a first time mom I’m always so worried I probably call the doc office once a week (yikes). But when my kiddo doesn’t wear footed PJ I always put socks on her feet I’m sure that’s fine??? With winter coming I’ve been putting in fleece PJs and some don’t have feet should I still be putting socks on baby on night or let her feet breath? Ik I should probably only buy Jammies with feet but I also purchase ones without feet 😬.
