@Star nope just eggs! Everything else he’s had he’s been absolutely fine x
Definitely sounds like an egg issue then. Give it a few weeks and try again, but leave it for about 4 weeks.
It’s totally normal when they have new foods to do every consistency and colour of poo! Their gut is changing. Unless it was accompanied by other symptoms I wouldn’t worry.
It does sound like a bad reaction to egg. Let his tummy settle then try egg again but in a well cooked form like a cake/muffin. You can home make this so it’s not sweet. Try it for a few days then move up to something with a higher egg content. You can look up the NHS egg ladder for more guidance
eggs usually are a mild allergic reaction so try again when baby is feeling a bit better and see if it’s the same reaction n
Sounds like it's too pure of a protein for his tummy at the moment. Did he react like that to anything else?
