How do I navigate this problem?

So my mom has always been around and very close to me. She said she’d look after my daughter when I went back to work but I said no don’t worry she’s benefit from nursery this was ages ago though. Currently my mom doesn’t have her any days. My daughter also goes to MIL’s which works nicely. Within the last year every time my mom has her, even for a few minutes she constantly complains to me about how bad it is. She has made up a lie before saying my daughter hated going to my MIL’s, which we found out was not true at all. When my mom does have her occasionally she doesn’t do anything with her, she will sit on her phone and then my daughter starts tearing the place up out of boredom or attention. I have offered to pay for entries to child friendly activities but she will not go with her. It’s my mom’s feelings after all and if she doesn’t feel comfortable that’s fine. But as her daughter I’m sad. I don’t have that person anymore I can rely on and it is affecting our relationship. Even today I need to go to a drs appointment and the way my mom rolled her eyes and was already telling my daughter off for nothing !! I feel drained.
