DS is 18 months .
I don't get on well with my SIL for different reasons . We had a bit of a disagreement at a family party a few weeks ago .
I told SIL that she was not to contact me and would not be seeing my DS until her attitude towards me improved .
She disagreed and told me she will see DS and it is nothing to do with me .
I told her it's my decision and she needs to improve her attitude towards me before she sees him . Her response was "we'll see ".
MIL watches DS for me one day per week . SIL isn't speaking to me but made a point of taking a day off work to go and see my DS at her house . SIL has not been to MIL for at least a year , so this was a deliberate act to prove a point to me .
I'm so annoyed . I'm also feeling powerless and totally disrespected as a mother .
I feel like she feels like she has rights to my son and I'm stupidly worried that she has rights to take him away from me .
I know it's stupid to think that , but it makes me so powerless and angry the way she has done it .
AIBU?
