you cant speak up because your throat chakra is blocked, you need to do sllowly build up your strength
it is your house and it is your child, you are in a position of authority, and MIL is a guest in your home
people like your MIL can sense weakness and they take advantage of it,
you just had a baby she knows that you're in a vulnerable state, she knows that you have anxiety.
the good news is that it doesn't take much to stand up to bullys like her,
all you have to do is assert your boundaries firmly and she will crumble, your MIL sounds like a very fragile woman
be prepared for her to play the victim
next time she tries to snatch your child, you need to put your hand out in front of you in a "stop" gesture and say "No" very clearly and confidently
she might try to keep going but you said no, and no means no, stand your ground and do not let her get her own way
when you feel your throat close up its because the chakra is blocked , you need to focus on nose breathing and neck exercises,
when your MIL comes around she is making you tense up and that can also manifest in your throat
there are many way to redirect that energy , you can put a rubber band around your wrist and pull it when your anxiety gets high
Also, do not eat or drink from her, you can accept the plate or glass ,
but do not eat anything she cooks or pours for you , leave the plate on the side and say you're not hungry if she asks questions
making somebody food and drink is very spiritually powerful
that is why you should never accept food or drink from someone that does not like you , bad energy can be transferred into food , when they are thinking bad thoughts about you
they can curse you through the food and it creates a lot of bad energy for you , can give you bad luck and misfortune , even make you sick
