This sounds amazing, Becca! I think weight is a huge factor with any travel product, particularly the car seat and stroller. Also, being able to open the stroller or adjust the handle of the infant car seat with one hand would be fabulous. Easy to clean on the high chair is a must.
Let us know how your thesis turns out!
My husband always joked that he wanted to invent a carseat that had a vibration feature to soothe our little ones when the car wasn’t in motion or when bringing carseat into house with baby still in it have it keep vibrating to continue to sooth and stimulate the car movement! As you can see we had some desperate moments coming up with these crazy ideas.
I think it would be amazing to somehow combine a true infant carseat with a convertible carseat. Our convertible carseat claims to also work for infants 5lbs.+, but there is no way I would put a newborn in it. It simply does not recline enough in the rear facing position. A swivel base would also be pretty amazing for easy loading and unloading (I know they make these, but I haven’t seen one with really awesome reviews).
