My son is 4 months and he gets held most of the time. Other times I put him in the carrier or in his stroller. When I put him in his stroller and bring him right next to me he is alright while I wash dishes or something. Some people think letting babies cry it out works but I don't want to do that.
She's only 4 months. You are her comfort and peace and as I know myself it's hard to get stuff done with a baby always wanting to be held there isn't much you can do. Your baby needs you the most in their first year of life. Maybe you can get a baby carrier so she's being held and your hands can be free
