Anyone use this Pigeon bottle? Seems that it needs a lot of energy to suck the water out from the straw, anyone can share experience? Thanks

Actually a lot of the straw cups are like this. Require more strength to suck out the water. It's a safety feature. Prevent lo from gulping too much water and choking.

I agree with you on this too! It feel that it needs alot of strength for the milk to come up!

check the straw alignment and the valve. sometimes it's too loose.

I've not seen this before. where you got it from?
