Is it nursing strike or something else

F • Mom to 👶 3/13/22 🌈

My LO is 9w4d and he has been refusing my breast since two days. He is someone who feeds to sleep and constantly on my breast for comforts. He has been acting weird and cries when i am offering him my breast, refuses it but he has habit of sucking to fall asleep so i offer him my pinkie finger ( I am not planning on using binkie until he’s 6month) and he instantly stops crying and keeps sucking and then i again try to offer him my breast, he would starts crying. I kept switching from the finger to breast until i succeed to fool him but again he falls asleep and barely eats for few minutes. I don’t know if this behaviour is common or is it a new leap or my baby is sick? Anyone went through the same thing?
