How do you ask your mum to be more involved in helping with the baby without hurting her feelings?

It depends on how much involvement you want. Other than wanting our freedom, the new generation of grandmas also prefer to have their own freedom and personal space. Take for example my mum who is 50 this year and still actively working. It doesn't make sense for me to ask her to stop working as her income is quite difficult to compensate for, and she has more social activities than me. Haha. Sometimes when I go over to my parents' place with my bub over the weekend I don't get to see her until night. It's also not fair for me to ask her to stop working or enjoying herself as that would be pretty selfish. As and when she is around in the house she helps to entertain and take care of my 6 month old. I can't ask for more, it's my baby anyway. You could probably engage your mum more during playtime with your baby so she feels more connected to your baby and will naturally be more involved? But it really boils down to what kind of personality she is.
