My baby keep crying non stop and drink like 20 ml milk only compare to his normal 120ml~ Thursday I bring him for injection and he got fever for like 2 days. Today he keep crying since yest night and drink very little formulas but when I breast feed him he still will drink but my supply is low so normally I need to top up formula, but till today he never drink much formula~I m not sure if he is teething ~ anyone got this experienced?
