Baby elephants really do suck on their trunks! In fact, they suck their trucks just like baby humans suck their thumbs, and they do it for many of the same reasons.
Thumb sucking is totally normal for babies and toddlers. During pregnancy babies can even be seen on ultrasounds sucking their thumbs.
Why do they do it?
· Newborns suck for feeding. It’s a natural reflex to satisfy hunger—older infants may keep sucking as a sleep or transition routine.
· Sucking calms and comforts—you might notice your child sucking their thumb while holding a blanket or curling a strand of hair—these are common signs of self-soothing behavior.
· Babies use their mouths to learn about the world (oral exploration).
· Sucking can ease teething discomfort or provide sensory input.
· Children sometimes increase sucking during illness, change, separation, or other stressful situations.
What can I do to help them stop?
Children usually stop on their own between ages 2–4, and most stop by school age without problems. If your child continues to suck their thumbs or fingers, they may need help to stop the habit. Staying calm and supportive is key—avoid shaming or punishments.
· Use positive reinforcement: praise and small rewards for not sucking during target times (e.g., at school).
· Address triggers: soothe separation anxiety, improve bedtime routines, offer comforting alternatives (teethers, soft toy) if appropriate.
· Substitute sensory activities: chewy toys, teethers, or fidget objects for older kids with oral sensory needs.
· Use gradual behavior plans with realistic goals (reduce at daycare/school first), and visual charts.
When should I be concerned?
If your older child is still sucking their thumb frequently, or you notice changes in their teeth or speech, check with your pediatrician.
American Academy of Pediatrics: The good news is that most children stop their sucking habits before they get very far in school. This is because of peer pressure. While your child might still use sucking as a way of going to sleep or calming down when upset, this is usually done in private and is not harmful. Putting too much pressure on your child to stop may cause more harm than good. Be assured your child will eventually stop the habit on their own.
