The last three days I’ve noticed my 3 month old is throwing up pale brown liquid. There’s no blood in it and it’s always after a feed as is usual, though it used to be full on milk she’d throw up rather then this saliva brown colour. I’ve googled it and lots of worrying things come up and I’m usually a massive worrier myself but the only confusing thing is she’s totally happy, laughing this morning and moving around as normal and interacting a lot. She’s also had her usual feed. Has anyone else experienced this and is it normal?
