We got this great new Johnny Jump Up from my sister-in-law. Thanks Tara! We put Owen in it last night. He was a little grumpy to begin with, but seemed to like it ok. However, when he got really going with his little legs and was bouncing all over the place, he almost bounced his little head right into the doorframe. Hmm. Ladies? Mommies out there, is there a way I can avoid a little Johnny Jump Up collision? Am I using it right?
