Switching up bottles?

tonychelle

We have been using Nuk bottles since the hospital provided those when we were having latching problems. and I continued using the Nuk bottles at home pumping and now FF. I think she does really well with them, so I'd like to continue using them since we have them.

I wasn't planning to use those, so now I have some Dropins that I had planned to use, as well Dr. Browns and VentAires from my baby showers that I kept as backups.

My question: is it hard on a baby to switch up bottles every so often (like if I continue the Nuk but also use Dropins/etc) or should I just try to get rid of all of the others and stick with the Nuks? (I can't return the Dr Browns because I accidentally tore part of the packaging, but I could possibly return the VentAires and Dropins, although I like the idea of Dropins better than the others...).

Anybody have any success/failure switching up? Maybe I could at least wait til later since they are bigger bottles...
