Re: Gas toh thi hi.. ab constipation bhi!!! 
Yup I am bf her, but NOT exclusively.. like i used to give her once (sometimes twice or thrice) formula (almost 2 oz each feeding)…
I started off sippy cup just a couple of weeks ago, and that too her doc recommended.. he said its better to switch baby to it from bottle, because it may decay baby’s teeth as formula are more sweater than mother’s milk.. she is ok with it not too friendly. Although i have just started giving her warm water along with gripe water in sippy (no milk yet)
Thirdly the cereal I am talking about (milupa 7 cereal), yes you are right its for 6+ but thats written in every cereal (and every baby food) isnt it… before that i have started rice cereal and wheat one and they also said the same… still i have started them from 4 months (eeh pretty early i know, but then i reduced the dose bcoz her doc said so NOT bcoz she got some allergies or so)
