15 month old development delays

[Paapaa]

Hi my 15 month old is only just starting to sit unaided, we can't leave him as he will chuck himself back. He's rolling around but not crawling, pulling himself up and its very hard to get a laugh/giggle of him. He can say car and peppa but nothing else. He's bin referred for physio but just wanting to see if anyone gone through this, what happens and how long till you noticed a change. Thanks

I'm sorry, I don't have any personal experience, but you might be more likely to get replies from people who do if you repost this in one of the Special Needs sections. Those boards can be a little bit quiet, but there are some very experienced and helpful posters.
