Hi my lo is 11wo and was awake all night last night!! Fussing not from hunger i dont know why.. he was fighting swaddle .. which he still def. needs because he hits himself in head and wakes him self up if he isnt wrapped up..! Doctor says teething probably not, that it may be gas.. but he has been on same formula for 2 months and he gets gas drops in every bottle.. He has recently started to chew on the nipple of bottle and not eat as much.. wondering if he is beginning teething ?? Doc wont see us for a few days and says it is probably not teething... just wondering if anyone could help me out??
