You can use it for up to 4-5 months. But at 11 weeks, I probably wouldn't bother if your LO is comfortable in the carrier the way you're using it :)

I got the heart-to-heart at 3.5 months, and by that time I think I already passed the time period of being able to use it with my son. He's in the 90th percentile for height, so maybe that makes a difference. I'm pretty sure it would have been perfect for him for the first two months, though.
