My view is gonna be different here, you dont want your mil to stay with you(with GC) is that triggering your inner peace? If youre exhausted with your toddler just remember it's phase, it will settle eventually.But remember to build a cordial relationship with your MIL. Involve her to play with the kid esp when your H is around,tell her she is not this interested with the kid when her son is not around in a funny way. Dont take things to your head. This lockdown is tough on many of us.Youre not alone! Keep your cool.
