Yes my DD at 18mos still needed a morning nap but for only 30min....then a 2.5-3hrs one in the afternoon! Now at 29mos (almost 2.5yrs) she doesn't have a morning one but very much needs 2+hrs in the afternoon or we'll have a demonic child on our hands. When family say "oh just let her play, she'll nap later" I get SO MAD and a few times I didn't nap her just to show them. Come dinner time 5-6ish she's almost flipping tables! That's when I smile, they then say "oh I see, she needs a nap" _ "oh no, it's too late now for a nap....now you can go ahead and entertain her until bedtime since you "know better" :P Seriously I did it twice and now no one questions what I say she needs.
