We are similar, just seems to be hundreds of books everywhere. We’ve got this in the living room and got this for the living room. We bought some boxes to fit on the bottom so could have more books in there too or toys. https://www.dunelm.com/product/kids-bookcase-with-storage-white-1000203189?defaultSkuId=30825986&branchCode=0137&utm_source=google&utm_medium=cpc&utm_campaign=KKids_Bedding+%26+Accessories_%5BGOO-LIA+PSB-KIDSACCESS-ACCESSORIES%5D&gclsrc=aw.ds&gad_source=1&gbraid=0AAAAADGqyX0PCtcLqT08ALdgi7NRrME5o&gclid=Cj0KCQjwhMq-BhCFARIsAGvo0KcvcrPxYyDkyewdYxsTdByLJlcp3kUWzK2w72JHLQZba_rDgDJCMwUaAuUyEALw_wcB

I love that you have so many. We can't buy any because my son eats them, literally. He loves books, but us so destructive. The one above is what I seen most for toddlers. They have three at daycare and there was one at playcare.
