Thanks heaps for thinking of us.
I returned to doc. Ears are fine, he hasnt put on any weight which is a bummer. Im supplementing for feeds too. But honestly, I feel like your routine suggestions are helping the most. Over the last few days, he has started settling well at night and waking 4hrly. He is taking big feeds when he wakes so I feel like some of the night wakings are genuine hunger. Given his weight and height gain over the last 4 mths has been poor, Im happy to feed a few times a night if needed, just not 2hrly.
The first few days, I was able to get a long nap am and short pm, but now he is refusing the late afternoon nap, even if I do a short am nap, which is being tricky, and making for many night wakings. So, I think you are right about stretching out to one nap because even today we were out about and he didnt nap until 5hrs wake time in the morning and he was happy the whole time. Only problem is, he awoke 1hr later at 1.30pm when we got home and refused his afternoon nap. He was asleep by about 6pm and didnt seem overtired, happily self settling himself to sleep. Im nervous how the night will go. I hope it will be ok.
