Well, I'm not too sure why you'd be feeding your baby toilet paper, but no toilet paper can not kill your baby, it may just make it sick. Cellulose or plant fiber is the main ingredient of toilet paper. It cannot be digested by humans but in small quantities should pass with no problems. It is the pulp that is found in fibrous plants. Any vomiting, constipation, abdominal distention, or abdominal pain warrants a trip to the ER. Just want to add that your baby will have at least 3 - 4 years of putting things into their mouths or up their nose! LOL The worst time is teething time and babies love to feel of certain things on their sore gums. Toilet paper (a small bit) should be fine and pass through the digestive system as the above poster stated. Get baby proof bars for the lower cupboard doors where you keep your cleaners and the bathroom is the worst place that you have to keep your baby out of. If you phone your poison control they will give you a pamphlet of what to do if your baby should ingest anything poisonous until the ambulance gets there. Watch your baby out in the backyard during playtime. My girlfriend years ago had her son out in the backyard and he ate half a slug! Because people here in B.C. put slug bait out I was worried this slug could have crawled through some of it so I got her to give her son a little milk (to coat his stomach and contain the contents for a short time) and to put the the other half of the slug in a jar and phoned I phoned the ambulance. Thankfully everything was just fine.
