Quick question ladies - How can I get Olivia to drink out of a straw? I demo it for her and she gets all excited then she just holds it between her gums and looks at me like 'now what?!' I am trying the straw cup as it has been really hard to get her to drink from a cup with a spout (I have tried 3 different kinds). Now with the weather heating up I want to make sure she starts drinking more water.
