With time, your little one has grown sharp both mentally and physically. Allow your baby to try out new things regardless of the fact of success or failure. Trial and error is a wonderful way to let your toddler gain knowledge through his own understanding. You can offer basic puzzles which are an excellent source of helping your baby get familiar about problem solving.
What you need to know
You need to act supportive when your baby is trying to solve any problem. Be it untangling a shoe lace, matching colored blocks, etc., you need to be there to motivate your toddler’s effort. Also, offer help whenever your little one goes clueless. It is a process in which parents need to act as a guide.
