S.H.
You are going to need, file cabinets no matter what.
And, projecting ahead, this will be for YEARS... of information for each year your child, grows up.
Then, for school, too.
And you will need the space... to store all of this.
Per file cabinets or bookshelf, space.
As time goes on, you will know what you can purge, or keep keeping.
Because it will accumulate, a ton of stuff.
