Hi Elin. If English is your second language, yours is quite good!
We sailed with babies. At one year old, we used a typical baby carrier which the baby mostly sleeps in.
It was like a basket with a handle. And it doubled as a car seat with the baby strapped in the carrier and the carrier secured to the seat belt. That works well getting the baby on and off the boat and gives a good place to nap in the cockpit or cabin.
At about 1 to 2 years old, we used the Vee berth as a secure place to sleep during the day. In our case, I put together a frame with nylon screening (doubled up for strength) in it that closed off the Vee berth. You may have another berth on the Bavaria that could serve. The screen allowed us to keep an eye on the baby at all times. Ours loved the motion in the Veeberth.
As they got a little bigger and were walking, secure lee cloths in pilot or settee berths worked great. These formed safe play areas even in rough conditions. A safe place in a boat underway, where bumps and bruises are minimal, is tough to find.
Another favorite of ours was a secure seat that could be clamped to our table. Belted into the chair, they would spend a lot of time there, eating, and watching the fascinating sights of a moving sailboat.
A one year old that isn't sleeping requires a persons full attendance on a sailboat. That person (watching the baby) shouldn't be expected to do anything else.
Once they begin to walk, they simply have to have a correctly sized PFD on at all times above decks. And for us, they never left the cockpit under sail or at anchor, unattended. Never. Don't trust netting.
Cabs anywhere I think would be fine with a suitable baby carrier - seat.
The best thing we ever did with our babies was take them sailing, immediately.
