casual informal wedding wears dressed in summer

i need some advice. my baby hasn't been gaining any weight. I only bottle feed so my boobs don't get any saggier. Any to save money I've only been adding a little bit of formula and just keep adding water. He's getting full, so i don't understand why he cries all night and isn't growing. Is he just being a brat? I have been watering it down more lately and think hes just spoiled. what do you guys think? casual informal wedding wears dressed in summer
