14 month old waking in the middle of night hysterical

[curly173]

Im wondering if anyone else has had a similar issue whereby:
We had a perfectly sleeping baby who generally slept all through the night. On occasion I would hear him in the night cry out, but usually he put himself back to sleep immediately, which made me think that he was just turning over or something. At worst, he would have a grizzle for 5 minutes and then go back to sleep.
However in the last 3 weeks on some nights at approximately 11:30 or 2am he is waking up and is crying uncontrollably.
There are some things that have changed, but I cant put my finger on one thing to single it out.
I was the person who put my son to sleep every night, but my husband has offered to do it (Im 8 months pregnant and a bit uncomfortable) which has been great for me, but as its not a consistent thing (sometimes I feel fine to do it, sometimes I let him) and Im wondering if this is an emotional trigger for him.
Also we seem to be slipping his afternoon nap on occasion as sometimes he looks like he can last the distance. That is, DS is having a 1 &1/2 hour nap in the morning (from 9:30 - approx 11am), he was having a 1/2 hour nap in the arvo at about 2:30pm, but lately sometimes he didn't want it or I would directly push him to his 6pm bed-time of which he would drink his bottle of milk and virtually fall asleep in our arms and put him to bed without any settling on our end, which was great at the front end, but sometimes we end up with this screaming episode at 2am, which could be the other possibility, that is, he wakes up at 2am and wonders "what happened??! I was playing last thing I remember...."
At some stage in my wisdom, I fiddled with his teat and pin-*****ed a few extra holes to help get the flow going a bit faster for him as I thought he might have been struggling. When the screaming started, I thought he might have had a belly ache, so we removed this, but the only thing that changed here was that he didn't wake up after 1/2 hour of initially putting him down. Although I havent returned to my home made teat either......
I thought for a while it might be diet, but there is not one thing that seems to trigger it more than anything else. His diet is still fairly basic and no new things have been introduced lately to disrupt the status quo.
Im at a loss as to why he wakes in the middle of the night. My husband (the true angel he is ) got up last night, gave him a small bottle of milk, changed his nappy and re-settled him and after a 5 min protest, my son went back to sleep really quickly (previously we could have been up for anything up to 1hour & 1/2).
We think there might be teeth, but there are no obvious signs of them arriving any time soon and if we go to our son, he stops crying, which to me is not a physical pain thing otherwise he would keep crying.
Im open to suggestions, comments and any other questions as its such a random thing and all I want (as we all do) is a happy baby that sleeps through the night.

It could just be night terrors, Jordy has had them a couple of times.
