I have a couple of Infantino carriers from my first. I'm currently pregnant with baby #2 (and probably last), and I plan on doing a lot of baby wearing since I have a 2 year old to chase around. Is it worth it to upgrade to the Ergobaby? I don't really have any complaints about carriers we have. They worked fine for my son, but everyone says the Ergobaby is more comfortable to wear, so I'm wondering if I should upgrade. This is probably our last baby, so I'm not sure if I should spend the extra money. Thoughts?
