The key is to stop telling MIL about your mom being there. DH has to avoid this as well. This will possibly help.
Start inviting MIL on outing. "MIL we are going to the zoo on Saturday and would love for you to join us!" "MIL we are going to the park on Thursday morning why don't you meet us there?"
Basically invite her to things so she has the opportunity to be part of her grandchildren's lives. If her weight prohibits this that is not on you.
Why would anybody invite someone to an activity what will be a physical hardship for them. That idea is so cruel.
