Sleeping arrangements

Megan
Need a little advice ladies! We already have a small basinet in our room 
My brother is a carpenter and has been really wanting to make us a cosleeper that will look like this 
Would it be overkill to have both? We really love the idea of a cosleeper but with already having a basinet we are wondering if we really need both. Not to mention, storing both after only 6 months use max. Our room could fit both but it's not huge so it may make it a little cramped. Any suggestions or advice?
