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?

i don't know exactly how old your baby is or what vaccination was given, but yes, fever and crankiness and sometimes even a loss of breastfeeding is common after a vaccination. if the fever does not subside in the next 2 3 days please speak to the doctor. in the meanwhile, feed your baby as per demand, whenever he wants. feed your milk and if he is still hungry then try the formula. you can also keep massaging his gums if you suspect he is teething
