That sounds massively annoying Springer: hopefully "just" an admin cock-up. Do you have the name of the Paediatrician you saw? You may be able to find a phone number or e-mail for them so you can check with them directly?
MissMalteser failure to hit physical milestones was actually the first thing we spotted with DD. She was very late to pull to stand (not until after 18 months I think), late to walk (nearly 2) and was always very hesitant on play equipment, didn't want to jump, etc. etc. As a baby she hated having weight through her legs - if you'd try to hold her with her legs on the ground she'd pull her knees right up to her chest. She went downstairs on her bum for ages. To be honest I wasn't that bothered by it as it worked and was safe. But she has only been using alternative feet to lead going downstairs for a few months.
We got a block of 10 physiotherapy sessions when she was about 15-18 months I guess which were great to get her standing/walking. After that we found Gymboree great. It took a lot of work as we had to encourage her to do things that were a bit outside her comfort zone (to begin with she just wanted to sit and play with the balls, though she always loved the bubbles and parachute games, so we never had any trouble getting her to class), but now (just 4) she loves to climb and jump, she is super-fast on her scooter, and properly got the hang of her balance bike about a month ago (having really not wanted to go on it at all until a couple of months ago). She is still not that confident with swimming but we're working on it. She does ballet lessons which she loves, and yoga and dance at school.
I still wouldn't say that she is as skilled as her peers in anything physical BUT she really enjoys it which is all we wanted, because it means she can take part in everything without getting too left behind.
I just noticed people up thread were asking for tips on speech. I really like Walkie Talkie Speech Therapy on YouTube - she has lots of ideas/examples of games to encourage speech and break it down into little achievable steps. Mainly aimed at toddlers rather than older ones, though there may be videos for older kids too.
