Do not let what you cannot do interfere with what you can do.
If your child has certain special needs issues and invited to a birthday party, try to include them as much as possible in environments where they have the best chances of success. As a parent, you know the environments or situations that often are going to be successful or unsuccessful for your child. For example you may opt to skip the jewelry-making portion of a party if your child has poor fine motor skills. If your child doesn’t swim, you may not sign on to the swimming portion of the party. Find out the party’s schedule and bring your child when they are eating, opening presents, or doing other activities your child can successfully participate in.
Students with fine motor issues may need special pencils. Some require special grips, triangular design, rubber sides, or unbreakable lead.
