We always refer to the recommendations issued by the EU health authorities. They have not yet issued any specific recommendations for the use of the baby hammock.
Basically, our baby hammock is a sleeping aid and does not replace a normal baby bed. You can therefore adapt the duration individually to your baby's needs. There is no rule you have to follow.
Your baby may, in principle, sleep in the hammock for as long as necessary. However, we recommend that you use the baby hammock as a supplement to a real bed, as your baby should also be able to sleep on a firm mattress.
If you are unsure about your baby’s sleep pattern and needs, we recommend that you speak to your doctor or health visitor.
