In Islam is it wrong to do kind things and be nice to those whom you love such as your mother or siblings simply out of love for them? Or is that falling in love with dunya?

I always here you only do things for the sake of Allah and his please but things such as giving charity and doing so many good deeds we can do to gain reward from Allah only for his sake and pleasure but what about doing things we want to do simply from our feelings such as buying our loved ones gifts and just making them happy in life.

Would that not count as doing things for the sake of Allah? Is love a wrong thing then and us being deluded by the dunya?

it feels like such a heartless mentality....
