Leaving your child to enjoy an activity on their own can be difficult the first time you do it, you may not initially want to leave them, and they may not initially want to leave you.
Specifying the time that you’ll be back helping to relieve any uncertainty, as does gradually increasing the amount of time your child is at an activity without you and being clear that each increase in time is benefitting you both. Talking with the staff at the club to arrange support and make yourselves more comfortable with being in different places is a great way to prepare, then standing outside of the hall and chatting with other parents at an activity for just five minutes is all it takes to start.
After being apart, rewarding your child for any time spent independently is important too. Anything from saying “well done for having a go on your own” to talking about their new friends and what they did at the club is a great way to do it. You both missed each other and that’s ok because you both enjoyed your time doing different things.
If you're concerned about other people understanding your child, then using a Communication Passport may benefit you. A Communication Passport is a small booklet written from your child's point of view that describes their needs and the best ways of supporting them - this may be especially useful for children who cannot express their needs or those who aren’t quite ready to talk personally about their support yet. Your local sensory support services can help you develop your child’s Communication Passport.
