No speaking - literally!

Ok, so I've posted my concerns bout DS before. But I'll do a refresher anyways.

DS is 2y5m in a few days time and he doesn't talk. Period. The most I've gotten from him is 'mumumumumum' and he babbles.
The thing that concerns me is that he used to talk and say a few things and have a decent vocabulary ('again', 'all gone', 'tata' just to name a few) and just before I found out I was pg with DD, just suddenly stopped saying them.
He's only just got 'mum' back, alternating; sometimes saying 'mummy', 'mumum' or 'mama'

DH is getting frustrated because he never says dad or dadad as much as we repeat it to him - causing me to get peeved at him so much because of the comments DS generates from DH because of that.
Here's just a couple of the gems.

'Well, looks like its all up to your sister now to be the shining star'
'Don't bother, he doesn't understand'
'Don't bother, he's never going to say dad'
'We might as well push your sister to do stuff, cause your not going to be a superstar'

There's a couple more I wanted to put but I can't remember them now.

Anyway, thing is, we're on the wait list for a speech therapist, audiology appt and OT and have been waiting since November last year. We were told that the hearing appt would be pretty quick to get into - and we're still waiting on that too.

Theres other things that concern me too with him.

* CHN and other people say that he should be 'feeding a bear' and 'making a cup of tea' and stuff like that - he doesn't do that, doesn't really understand that concept (but he does try to feed DD - by shoving the bottle in her mouth )
* He hates anything on his head or feet (but he's slowly getting used to shoes on his feet because of daycare)
* He doesn't imitate noises - eg a car honking its horn. He never used to push cars and play with them in the proper way. He does now but still doesn't do the noises
* He doesn't do what we ask. For example, we ask him to get his shoes but he just runs around. We ask him to get stuff and he doesn't. The only thing he does do are things that we point to and say 'Ta for mummy'
* He doesn't answer his name or acknowledge we've called his name out.
* He doesn't want to try new food, as much as we try
* He doesn't use a fork or spoon - even though he knows how to cause he used one from an early age.

Is there ANYTHING I can do? Honestly, it's starting to REALLY get to me now (I hate reading things online cause it gives me the worst outcomes - I currently have 9 tabs open reading different stuff)
Besides the wait for the audiology appt, speech and OT?
We really can't afford private speech therapy and I just want to see SOME kind of improvement soon.

Sorry for all the rambling
