If and how to store baby stuff

Hi friends,

Hope you can help my family with this dilemma. The mountain of baby stuff continues to grow as my LO grows, and we dont know what to do with it.

We live in a very small house so there is not much storage space for more than regular items and some Christmas decor under the stairs.

We have a nice outdoor wooden building but it is not climate controlled. My husband thinks it would be fine to put the baby stuff out there- stored in plastic containers and what not.

I have concerns that outside might somehow damage things? Idk, this building is great. We've had our Christmas decor out there before and had no issues with moisture or critters.

What do you think?

The building?

Inside?

Or just get rid of most everything and start fresh when/if baby #2 comes?

Thanks for your input!
