I have not extensively gone through the spells on here, but there might be.
However it is best if you try to bond with your mother without magick. It just seems better that way, to not use magick for everything.
From my research, there are many ways to do this. I don't think that the website has something of this sort, but you can easily write a spell to do so. Use some red and pink candles, and do some knot magic to show the tightness of the bond. It might also help to have some rose quartz if possible. I hope everything works out for you.
