Hi,
Strong willed children are having strong self resolution. We can't assertively confirm about the same in a very early age. If you feel your child is strong willed , please try to understand his behavioural pattern. Their behaviour can be stubborn/determined, self experiencing/ creative, bossy/ leadership, impulsive/ prompt, difficult to convince/ logical etc. Parenting has far reaching impact in Shaping their behaviour positively. Parents need to hold positive perspective while parenting . They need guidance to understand and mould themselves.
