Your baby will probably try walking up the stairs once s/he learns walking. But before walking, s/he will be climbing the stairs by crawling.
Once your baby starts moving, it will be difficult to keep the little one at one place for a long period. If s/he can crawl, s/he will try experimenting by crawling up the stairs.
- 5 to 12 months: Your baby will first start climbing stairs by crawling. You should encourage your little one doing so before s/he feels confident enough on her feet. Crawling up the staircase will be easier than climbing down, which is far more hazardous as the baby may miss the mark and tumble down.
- 13 to 18 months: Even if your toddler starts walking, s/he will prefer crawling up the stairs as it’s more comfortable and easier. Try to hold your baby’s hands and take him/her up the stairs if s/he is able to. With a lot of practice, the baby will gain balance and more confidence and may even try to let go of your hands.
- 18 to 24 months: If the child is able to get enough balance and take steps holding your hands, introduce him/her to the hand rail and the walls to take support. S/he will probably need support to climb up the stairs, till the time s/he reaches two.
The child may also want to try out jumping from the steps. Allow him/her to jump from the last step while you stand as a guard right in front. S/he may also want to put her hands or legs through the rods of staircase handrails. Pay extra attention to these aspects of curiosity as they may prove to be dangerous.
You have to keep necessary safety measures like gates and other blockades in place to avoid any accident or injury. Give your baby plenty of assistance in climbing up the stairs. Encourage him/her to walk alone, but you have to be close enough to supervise every step he/she takes.
