Changing bedtime ?

My daughter usually goes to bed around 8 pm and has her last bottle around 7 pm. Lately she has been really tired at 7 and falls asleep during her bottle, I’ve been thinking about just putting her down for bed at this time since she’s so tired but I don’t want her to confuse it for a nap since it’s not her usual time. Do you think one hour will make that big of a difference?
