I currently have 396 size 2 diapers, is this enough?

I have 11 packs of size 2 huggies 36 ct (total of 396) diapers, will a baby use more than this? Should i start stocking up on size 3 now? Or continue with size two for a bit longer?
Update: No baby yet, just trying to stock up before they get here so i dont have to worry about buying it later
