Re: travel vs stand up swings?
We had both - someone gave us their full sized and we used it a handfull of times - it was big and bulky and I hated it - I got a small travel sized and loved it - we used it through mid - six months when he tried to crawl out. Took a proud mommy picture, washed it and put it away. It worked just as well when he was 4-5-6 months and no issues and he fit just fine. If it had a five part harness I'd still be using it.
Mom to my wonderfully sweet toddler who is the joy of our lives.
