As the child grows older, stuffed toys can provide an unsafe means to climb up and out of the crib. If the crib is new, make sure it meets the Juvenile Product Manufacturer's safety certification guidelines. Look for that seal on the product. Additionally, make sure all sleep wear is flame-resistant. When washing the sleep wear, steer clear of those dryer sheets because they can reduce the efficacy of the flame-resistant materials.
Electrical outlets are very intriguing to young hands.
Be sure to keep safety plugs in the outlets. Make sure they are placed firmly in there, but make it simple enough for you to take out when you need to use that outlet. My sons were able to pull these out at an early age. As such, in the areas in which the boys mainly play, my husband disconnected the power supply to those outlets. Keep furniture away from windows.
