Hi, I am 40 and mum to DS who is 2.7 (also am 22 weeks pg with my 2nd). DS has global dev delay, and was diagnosed with epilepsy (absence seizures) at 9m, was on anti-convulsant medication for this until age 2, but has now come off the meds and grown out of it. He had low muscle tone and made very little develomental progress until age 2, could sit at 10m but did not move, roll over or crawl, etc and did not reach out for toys or do anything much at all. He was a very frustrated child who couldn't even hold his own bottle, and needed constant attention and stimulation from me.
He is still behind but has made a lot of progress in his own way in the last 6m. He is still not talking or walking (though walks nicely holding one hand, just needs the confidence to let go!), and his fine motor skills are poor, but he now cruises, crawls, inc. upstairs, climbs onto furniture and is generally into everything, plays independently for long periods, and can post balls and small shapes into holes, and bring a loaded spoon up and into his mouth.
He has also had a history of glue ear and hearing loss and has just had grommits put in.
He is very affectionate, gorgeous looking (!)has a great sense of humour and an infectious giggle and all his friends at nursery yell his name as he comes in each morning, and are soon crowding round him and crawling round the floor with him (even though they can walk), which brings a tear to my eye just about every day.
