Can someone talk to me about sippy cups?

[Helgathehairy]

DD is 9.5 months and breastfed. I'm also doing BLW and she's definitely got the hang of it but doesn't eat loads.

She's never really taken a bottle but will have water from a Philips Natural bottle. She also has a tomme tippe sippy cup (one she has to suck to get the water from).

I read she should have a free flow cup?

I'm a bit confused!

A free flow cup is one without a valve, so if you turn it upside down, a bit of liquid will come out. If you have a Tommee Tippee first cup, that's free flow.
