My mother in law decided that I wasn’t going to be able to make it full term because I went into preterm labor around 25 weeks well here I am 38 weeks and 4 days , anyways

we had plans for her to come see the baby after she was born, and take her 6 year old grandson back home with her to visit for a while.. well she decided to come today and I’m not due until the 20th she leaves on the 15th. My husband said she isn’t taking the 6 year old with her because he willl miss seeing his sister. And she tells me I am not going to make it that far.. excuse me .. who are you tell me what my body is capable of doing ? Am I crazy ? Am I over reacting ? I am not going to make myself go into labor because you want me to
