I and my MIL have never really been the best of friends but I feel that now that am trying to start a family, I should get her more involved in my life. How would you suggest I do this?

You can start conversation by asking her questions e.g. her previous working life, travelling experiences, child birth and etc. I find eldery likes to share their experience in the past. I guess your MIL will be very happy to chit chat about her life. Also, you can send her some gifts during Mother's Day, her birthday, or special occasion such as mooncake, dumpling and etc. I find activities such as shopping, cooking and baking together are good ways to bond with MIL too. The most important rule of thumb is pay respect to MIL and accept her shortness and believe both of you will become a good friend. After having kids, actually I find it more conflicts between MIL as elder tends to give opinions and critiques on the child upbringing. The challenge will start after you have a baby. Thus, foster a good relationship even before you have conceived is a good headstart!
