Toddler always whining

My toddler recently is always whining from the moment she wakes up, she complains about everything and whines a lot, she’ll say she wants something so I get it for her and then she tells me she doesn’t want it so I take it back then she gets up and says she wants it again- it’s a constant back and forth with everything daily, I try different techniques and I know with circumstances with quarantine it’s more challenging out of routine which The past week I got her in a better routine but I just want to see if anyone else has experienced this? What works for you? I know every child is different Im just stressed! Thank you so much ladies
