First serated leaves?

Ok, so I have two plants ones a week old, ands the other is 4 days old. Is it ok if there both growing serated leaves but the leaves on the 4 day old are bigger and has them before the seed shell fell off?

The sprouts are probly fine dude, they are lik humans id imagine and grow at diffrent rates.

alright, thanks. im just paranoid, there like my kids.
