Thank you for your response, I'm sorry it's taken me so long to reply.
Since I wrote my original post we have been struck by yet another cold! But I have spoken to the health visitor who has advised me to get my son on solids and I have to say the difference in him over the last four days has been astounding, so I think you were right about the reflux not being as controlled as I thought.
He is still sleeping in bed with me but only after he has slept in his own cot for at least 3-4 hours....I do not want to co-sleep.
Unfortunately my husband is away (we're both in the military) and isn't home until Easter, we have no family that can help and we have recently moved so yet to have any local friends that I can ask.
On a positive note though my little man has started to go to sleep without any props except for his dummy
Over the last 3 days our routine has been something like this
A - 0530
E- 0600 - milk, approx 5-7 oz
E - 0730 - breakfast
S - 0900
A - 1000
E - 1000 5-7oz milk
E - 1130 veg purée
S - 1300 ( he usually wakes after an hour but goes back to sleep with dummy)
A - 1500
E - 1500 5 -7oz milk
E - 1600 veg purée
S - 1800
Then he stirs between 2000 - 2200 about every 15 - 30 mins until eventually he comes into my bed where he will sleep with 1 or 2 stirrings until 0300/0330 where we have a coughing fit intermittent within sleep til 0500.
I know I can't do any proper sleep training until my husband gets home and he has been a lot of better these last few days I just can't work out why at night he can't settle. Even if he only naps last 25mins he's wide awake and smiling? X
