I just started unswaddling my LO (11 weeks) and the good news is she's been sleeping great! But she loves to rub her face A LOT in her sleep and she's been waking up with scratches on her face. I try not to put mittens on her because I thought maybe she would like to suck on her hands but I hate seeing her face all scratched up. I do file her nails all the time but those baby nails are sharp! Do you put mittens on you LO to sleep? How do you help prevent scratches?
