Sometimes a child just seems to develop slower than other children. Children are all different, some develop language skills first and reach the motor milestones later or vice versa. Up to a certain level all kinds of possibilities are in a normal range.
You are the specialist for your child and if you got aware that something is not right anymore, feel free to contact me. We will have a valid assessment that clearly shows if your child is still within the possible standard deviation. If there is the necessity for intervention we will have a chat about the possibilities and the prognosis of the outcome of supporting therapies.
