Okay guys my daughter recently like within the last week has started to keep her eyes closed while playing ....

For example when she wakes up in the morning from a full nights sleep she will lay in bed playing with her feet but her eyes are completely shut .... she will only open her eyes when I begin talking to her .... at her 4 month checkup her sight and hearing was fine ... not sure if this is just a odd thing she picked up or I should be concerned
