I like it as a middle name My sister named her son Dylan Forrest (yes after forrest gump LOL) & he's now 16yrs old... it suits him & the girls like it too
His brothers name is Blake Valentine which the girls also like (he's 18yrs)

What ever name u choose will suit ur baby..... even if people dont "like it" at first, it will grow on them. If you both like the name Forrest then I'd go for it.... otherwise maybe as the middle name?
