I bought a structured carrier before little one arrived which is working well for us. I also purchased a seven sling because it was so cheap, but don't use it at all. I'm assuming I'll use it to carry LO on my hip later on but am thinking I would like something I could comfortably wear around the house etc. in the meantime.

My LO is almost 15 weeks and I'm wondering, how much use have you gotten out of Moby's, K'Tans, hotslings etc past this point? Is it worth buying yet another carrier? Are they even practical once LOs are a little older?
