My 86 year old mother in law (mil) has been living with my husband and me for 2 years. She has macular degeneration and hears out of one ear. She takes an anxiety med before bed. Also meds for gastritis and rheumatoid arthritis. She sleeps ALOT! Goes to bed by 9 pm. Gets up around 8 am, eats breakfast and sleeps again for about an hour. Eats at noon and then another nap. Is this normal? We ask about getting her out with others but she is reluctant to meet new people due to lack of vision and lack of hearing. She also takes over a conversation when she does see people. She is a former health aide who worked with the elderly. She loves listens to the radio and also audio books. Is this ok that she sleeps this much?
