Hi everyone, my son is 5.5 mos old and his enjoying some tastes of food but we're gearing up for the real integration of solids next month. So far, I ordered the Stokke Steps high chair (anyone love/hate while it's still returnable?) and a baby spoon. Are there any other MUST-haves for this phase? We live in an NYC apartment and I don't like to have extra stuff around if it's not essential or if I can hold off on the purchase for now. Thanks!
