Hi I just wanted to share my opinion, about when you decide to bottlefeed your baby. I would recommend
Avent . I got all types of bottles on my baby shower, the one with the inserts and the one against colic with the plastic cap on the bottom from playtex, well just putting these bottles apart and cleaning them was to much hassle for me, the Avent was more easier to clean and it had that system against colic too. The dr. browns bottle, seemed to leak..So I was pretty happy finding out about the Avent bottles. Easy to clean and you can put it together pretty fast. You don't neet to buy any inserts or so, or loose small stuff..I know Breastfeeding is the best, butif you have no other choice...from all the bottles out there this is what I really liked so far.
