Taking care of one's sister in Madinah Munawwarah without performing Umrah

Q: I came to Madinah to my sister who went through a big hardship. She is emotionally in need of me, she can look after herself now physically after recovering Alhumdillah. I did not come with the intention of performing umrah and wish to spend all available time to help my sister (I believe this is also ibaadat).

Will it be a sin on me if I do not perform umrah before leaving? I have never visited Makkah before. I am mentally extremely worried for my sister. I had always wished and prayed for visiting the Ka'aba but I don't want it to be a half-hearted visit.

Taking one's mother and sister on family outings

Q: I am currently living with my parents with my husband and 2 toddlers, my sister lives in her own house but has no kids. Do I need to offer my mother and sister whenever I go out with my husband and children like to the beach or for outings? My father does not take my mother out much and her only opportunity to go out for entertainment is with us. Sometimes I feel guilty if I don't offer them as I would not want to be in their situation one day but I like spending quality time with my husband and children only.
