Yes your baby is beautiful and good, the amount of hours she spends with your husbands mother won't affect that.
You're looking for recognition and validation from this woman, and you need to stop. It's causing mayhem in your relationship, which won't help your daughter in the long run, you're doing no good by pursuing this woman for energy that she is not willing to give.
just stop our daughter seeing her for the couple of hours a month all together? I'm concerned our daughter doesn't know her
If your real concern is that your daughter doesn't know her paternal grandmother, then stopping the minimal contact she already has won't help.
You mention that you're jealous, but thrashing around about it and letting it affect your relationship with your partner is getting nobody anywhere. Nothing good ever came from make decisions from a place of jealousy.
Try to accept the situation, get things back on civil amicable terms, adjust your expectations, and put all this energy into improving relationships with family that do make the effort.
