My 22 Month Grandbaby Just Had Surgery And The Hospital

My 22 month grandbaby just had surgery and the hospital admitted that they gave her too much morphine by accident. She was supposed to have 0.5 and the nurse gave her 5.0. She woke up the following day and seems to be fine except for minor things like not wanting to give kisses and very klingy with mom and dad. Could there be any problems from this in the future for her? Could there be any damage that we don't see? Thank you
