Could be the teething or just a phase. Our LO are next to nothing when she had a cold but back to it now
I posted something similar this morning. My little guy hasn’t really eaten anything for two days and is really agitated, he normally eats everything but is just clamping his mouth shut and blowing raspberries at me. He did nibble on some cold watermelon and a rusk earlier today but that’s it. I think I can see top teeth starting to push through. Hopefully it won’t last long for them both x
He will just pick it up again when hes ready, all you can do if keep offering food and maybe try softer and colder foods? Banana, berries, mash etc xx
