My LO will be 2 when LO2 is born, and I feel like a high chair is one of those things I don't want to need 2 of! But right now at 16 months, I don't see an end in sight where she wouldn't be in the high chair for meals....So when LO2 is 6 months and ready for solids LO1 will be 2.5.....will she be done with the high chair by then??
