My baby is 2 months, in general very calm baby. Exclusively formula fed. But since yesterday he has become excessively cranky and crying his heart out, also is refusing formula. He is barely drinking after forcing. Last time he had growth spurt was only crying, this time I don’t get why is he not eating. He also had his vaccinations done last week. Then we travelled out of town last weekend. He was fine through out. I need advice on this. I just don’t get why is he not eating 😭😭 could he be sick? All of us who travelled are sick now. He dosent have any fever.
