When your baby is ready to safely sleep with a pillow, don't toss one of your bed pillows into her crib. Buy a new pillow to protect her from germs or dust that have accumulated in your home, and pick a small, firm pillow. It need not be much larger than 12 by 12 inches.

Crib Safety. Pillows aren't the only danger when your baby is younger than 12 months old. Check saferproducts.gov to make sure that your crib model hasn't been recalled for safety concerns. Any fuzzy blankets, quilts or stuffed animals can pose a suffocation threat.

I never used a blanket in the crib with my daughter until about 2 weeks before I transitioned her to a regular bed. I wanted her to get some practice with sleeping with a blanket. She was 2 when we did this. I would not put a blanket in a crib for a child under 2 yrs of age..thats my own personal preference.

Babies and adults are different. A pillow can block a baby’s nose and mouth and can cause a baby to suffocate. On average, there are 32 infant deaths a year on pillows used as mattresses or to prop babies’ heads. The majority of these deaths involve infants in their first three months of life.

You can use a receiving blanket to swaddle your baby right away. But because of the risk of SIDS, you shouldn't use any soft objects or loose bedding while he's sleeping until he's at least a year old. After that, pediatricians have different opinions. Some say you can start using a blanket and a firm pillow. Others recommend that you wait until your child is 2, just to be safe, and use pajamas with feet or a sleep sack on cold nights in the meantime.

A baby should be at least 1 year old before being put in a trailer, say the AAP and other experts. Besides the bumpiness potential, there's the risk of a spill, so your baby will need to wear a lightweight bike helmet while on the ride, and his neck won't be strong enough to support one until his first birthday.

My LO is 9 months old and has been sleeping in his crib (not a co-sleeper anymore, yay!) with a light receiving blanket since about 7 months. He also has a pillow now, for about the last month or two. It's all on the parent and baby and how comfortable you are with it.

Baby & Toddler Rules. I have a friend who still cuts her son's grapes in half, even though he's in kindergarten. Another supervises her daughter in the bath even though the girl knows how to swim. And I'm already wondering when I can take the rails off my 3-year-old's bed.

My son slept in a sleep sack until he could sit up on his own (around 10 months) then I put him in footie jammies and a light receiving blanket. I started using a heavier baby blanket once he could stand on his own (around a year). He is 16 months now and over 25 lbs and he sleeps with a couple of blankets every night.

Stuffed animals. While the AAP doesn't recommend that babies sleep with plush loveys until they're 1, Ari Brown, M.D., coauthor of Baby 411, says it's okay once a baby is 6 months old, with these caveats: The stuffed toy is a small one (no bigger than the size of her head) and has no removable eyes or buttons.
