It's so cute!

That pot does not look "wayyy too small" and I don't think it will be in 2 weeks time either. I believe the rule of thumb is one inch of pot per inch of plant. Actually, as I understand it, if you put them in pots that are TOO big their root structure branches all out and I think that makes it a bit less efficient. I think it will be safe in that pot for 2 weeks, honestly.
