The first thing that jumped into my head (after sleep school, but then you have said that sleep school isn't an option so I'll leave that out ) is food intolerances.

I have my hands on a fantastic DVD called "Fed up" by Sue Dengate and it spells out the problems some kids have with food additives and general food intolerances really well. I think she also has a website so you could look it up. I got the DVD from my local kindergarten of all places so you could try the library or your local council for references.

As with all the other suggestions you have and will get, it might be, it might not be, but I thought I would put it out there incase...

Good luck, it sounds exhausting and insanely frustrating. Right at the time when you should be able to enjoy your little boy and family :hug":

ETA: I just had a quick scan through the website so that I was sure I wasn't giving you a bum steer and found a fact sheet that details the symptom of sleep problems
The effects

• insomnia
• difficulty falling asleep
• frequent night waking
• waking up too early
• restless legs
• ‘weird’ or ‘vivid’ dreams
• nightmares
• night terrors
• sleep talking, sleep walking
• sleep apnoea

Which food chemicals?

Reactions to food chemicals are a pharmacological - or food intolerance - reaction, not an allergic reaction to the proteins in foods.

The foods and food chemicals that can be associated with sleep disturbance include:

· Artificial colours, natural colour annatto, preservatives, synthetic antioxidants, flavour enhancers and flavours (more details below)
· Naturally occurring chemicals called salicylates, amines and glutamates
· Dairy foods are less likely to be a problem than additives and salicylates although dairy foods as well as the food chemicals above may be strongly implicated with stuffy/runny nose, snoring and sleep apnoea
· Wheat or gluten are less commonly a problem. However, wholegrain wheat in products such as wholemeal bread and cereals such as Weetbix are likely to be more of a problem than refined wheat products
· Sleep disturbance can also be the unintended side effects of the additives or active ingredients in medications, dental products and supplements.
· Some people are affected by VOCs – Volatile Organic Compounds – such as perfumes, fragranced toiletries e.g. hairspray and airfreshener, pesticides, household cleaners, renovation chemicals and especially chemicals such as flame retardants in new mattresses and pillows
