I changed from Avent to these when Stanley was about 6 weeks and his colic was CURED!!
So yes, you can change bottles anytime
We bought Dr.Browns recently to try and help Scarlett's colic but I swear they make it worse! She gulps air and it feels like she's racing on these bottles, dont understand how but the flow seems too fast and i think she's inhaling air thro her nose
