Yes, different toy hammocks have different weight capacities, which the manufacturer should specify. It's crucial to be aware of this limit to prevent overloading the hammock. Overloading can lead to the hammock sagging and even falling, which could result in damage to the toys and potential injury. If the manufacturer's information doesn't provide a specific weight limit, a general guideline is to fill the hammock with lightweight toys until it's about two-thirds full. This allows some room for the hammock to stretch without being overly strained. If you're frequently exceeding the hammock's capacity, it may be worthwhile to invest in an additional hammock.
