Completely normal! In a day or two, the cotyledons will open fully and let your plant begin photosynthesis.
In the mean time relax, don’t water too much and let nature do its thing!
Good luck!
Hello. Your seedling looks normal and is in good health. In a day or 2 the other leaf will open up to show the first leaves in the middle.
Your soil looks wet. No more water until the pot is light to lift. And no food until the first leaves are all the way out.
Good Luck.
Chuck.
