About to start 5mg dosage of Methylphenidate for my ASD/ADHD diagnosed little boy tomorrow - planning on hiding this is yoghurt as he is too young to swallow the capsule. If he refuses the yoghurt (PDA profile) can I sprinkle it into a milkshake??? Will this work? Thanks in advance. He so desperately needs to start taking this, I just need to work out how to get it into him if the yoghurt idea fails.
