My 9.5 months old baby has been sleeping more than usual since yesterday. She has no fever , she eats , she wakes up on her own after 2 to 3 hours , plays but she seems tired after a while. She used to wake up in the morning and sleep about 3 hours during the day and then the whole night. And now she sleeps every 2 hours for 2 to 3 hours. Called paediatrician, said to check if she has fever and she doesn't. Has anyone here had the same change without anything concerning?
