Rash on baby

[Kaayyyx]

Hey everyone, my 8 month old has come out in a rash on his stomach and back which is now spreading to his neck and legs. Does anyone know what kind of rash this is? He was on antibiotics so I don't know if it could be a reaction to them? He stopped them 2 days ago. Thanks in advance :)

Please ring your GP, it needs checking and no one on here would be able to diagnose correctly. Hope all is well,that's a cute baby tummy
