My 4 month old has had injections and is now sick. He is no longer sleeping more then 1 hour at a time. He can settle himself to sleep when he goes down but will not do it again after he wakes. I have tried to resettle him for about 1 hour at his midday nap after he wakes but this usualy makes him more worked up.He has about 4 naps a day and only is awake for 1 - 2 hrs in between. Do you have any suggestion on how i can get back into longer naps. He is staring to get a little better but still has a blocked nose and is due to have his 5 month injections soon which will muck it up again.
