Lollipop, I have two dogs that do that.
One is a big gangly lurcher who is always standing in the way whenever you want to go through a door.
The other is on a constant mission to get to the back door before anyone else - just in case they are going to go outside and steal her toy. (She's twelve, but she thinks she's a puppy. 
)
I have fallen over both of them today. 
We had another rollercoaster of a week really. Started ok, then we saw the paed about ds1's stomach and possible absences. Not only was it a complete waste of time, but he was patronising and rude.
Dh left for his course straight after the appointment, with me feeling all teary and wobbly (I blame the diet - and the paed of course) and when I went to fetch the boys from school (still feeling a bit pathetic) ds1's teacher came out red in the face, really aggressive body posture etc and had a go at both me and ds in the middle of the playground! 
She was furious that he'd shouted out to another child during class and not stopped when she told him to. She actually said "I was already angry today and I really shouted at him - in fact I got louder and louder, but it made no difference". Basically the gist of her tirade was that ASD is just an excuse for bad behaviour and she wasn't going to accept his dx as an excuse! 
I was too shocked to handle it well and ended up telling ds to apologise for upsetting his teacher. 
I cried all the way home, then sobbed on the phone to dh. My first instinct was to call the Head and lodge a complaint against her, but frankly was in no fit state and I certainly didn't want to cry on the phone. I also thought, ds still has to be in her class until July, so we need to tread carefully. Then I suddenly remembered the Inclusion Teacher that's going to be working with him/us told me to call any time if I had any concerns. So I called her, sobbed all over her secretary and her boss called me back! Very useful. Found out a lot of about his teacher - unbelievably, she has had several ASD children in her class in the past (I would have put money on her never having come across ASD in her classroom before) and has had help and support from the Inclusion Team before, but just doesn't (or won't) get it. In fact the lady that called me wasn't surprised at all. 
I also found out that the service hadn't had any involvement with the school for a very long time, until I kicked the school's butt and effectively brought them in myself, but now they are starting to work with several children in the school.
Anyhoo, the outcome was that the boss lady, called and emailed the Head herself and insisted they arrange ASD awareness training for the staff asap. She also said she will back up my push for safe space for ds to retreat to and make sure the teachers are made aware of an appropriate strategy for when 'they' feel like they can't cope.
Other than that, I had two nights with less than two hours of sleep (dd has a horrible cold) while dh was away, but the dcs all behaved really well and we coped. Ds1 had a school trip which he loved and Thursday and Friday he had two lovely days at school (different teacher).
So, as I said, another rollercoaster.
I have taken the day off today and spent it generally making a nuisance of myself on mn while dd systematically wrecked the living room and emptied every toy she owns all over the floor.
