when do you start using diff bottles/ nipples. like what age normally?

My son uses 2 and has been using them since he was about 2-2.5 months

okay thank you @muva.mermaid

So they should of started using different nips by now ? Jw because I Breast feed but I have to trick my daughter into taking her medicine through a bottle with the breast milk. She is 5.5 months old and I am using Dr. brown bottles

@muva.mermaid,

I'm not sure I know the flow is different and with the number 1 nipple my son fusses bc it's moving to slow for him. But he has to burp multiple times with the 2 nipple. I use avent

Oh okay! Because when she uses the bottle regularly she burps once and then she is done.
