Parent Sims Carry Infants to Pool Edge for Naps Instead of Using Nearby Beds

When I try to have an infant take a nap, the parent Sim always tries to go sit at the edge of the pool, which is causing a lot of trouble.My Sims live on a 50×50 lot, and there are plenty of beds, sofas, and chairs along the way, yet they insist on carrying the infant all the way to the pool at the edge of the lot.Please tell me if there is any solution other than locking all the doors leading to the pool or building a pool inside the nursery.
