Send them!
You are obviously a loving person, who knits from her heart!

Knit from your heart

, send them with love

, and she will love you

for it!
I couldn't have enough knitted things!
And everyone knows the Gramma is crazy in love and was knitting from the time of the ultrasound! You can never outdo the Gramma!

And who'd wanna try?

(Can you tell, I'm a Gramma, a crazy in love Gramma!)
I agree with others who said send the small items that you've already made, but quickly knit up a size 2T sweater to send with them. A simple style with beautiful yarn and adorable buttons as the eyecatcher.
I gave a little set of sweaters to a close friend, but only made one in newborn size. The largest one was 2T.
She's since told me she was so glad to have something for him at size 2T cuz she was OUT OF CLOTHES!
No one gives sizes 2T! 3T, or 4T!
