Blocking can only help (a bit), if you used natural fibers like wool or cotton. I can't tell from your photo or post if you used acrylic yarn, which will not block.
I echo the advice about a border to make the outside edge more uniform.
Good luck with it! It's a gorgeous pattern!
This looks so great!! I'm glad you went for the blocking and can now confidently give it to your Godchild. They'll love it!
