Here’s Genna sleeping in the Hammock at 15 months:
Obviously, it still holds her just fine. It still holds my son (55 lbs) and me (110 lbs) just fine, as well. It’s perfectly safe. The only thing I really worry about is Wally forgetting she’s in there and running into her, waking her up. Also, I wouldn’t leave her in there awake or unsupervised while asleep. She only sleeps in it when I’m working – since it hangs in my office.
