Yes - he's pretty much impossible to resettle! I do try - but he can keep up the screaming for 45 minutes so I often just get him up straight away.
The problem with the morning nap is that he'll normally do a short nap (40 minutes). So we decided to start capping it at 40 minutes because then at least I'd know when the 2nd nap would be! It was getting so unpredictable. Also, when he did do a longer 1st nap it was very very rare to get a decent 2nd nap even with a longer A time. He doesn't usually get 3 hours of sleep during the day (he may or may not need it - who knows!?) it's more like 2-2.5 hours. So I think two 1.5 hour naps would be too much for him possibly. The other day he did a 40 minute nap, then a 1.5 hour one - waking at 2:40pm. He then refused a catnap and went to bed at 7pm. He didn't wake up until his usual 3 hourly wake up and didn't sleep any worse (or sadly any better!) than usual and didn't seem overtired even though I would never willingly keep him up for over 4 hours!
I think ideally I'd like to get an hour out of him in the morning and then a longer 2nd nap - and get rid of the catnap. Once the clocks have changed I will start slowly pushing the A time in the morning to see if that helps. He did 2 hours and 50 minutes (he woke early) this morning and still only did his usual 40 minutes.
One thing that has happened in the last two days - 2 teeth have started to come through (front bottom) - his first two! I would love to put the last month of terrible nights down to teeth but don't believe I can! Giving him meds makes no difference to his nights.
Another thing - I was reading another post on this board and realised I should have mentioned that DS had silent reflux when he was younger. He was on meds for that but it upset him, so I literally cut everything out of my diet that might irritate his reflux, raised his cot on a slant and he was much better - it had basically cleared by 5 months. Anyway, since we've been on solids, a few foods have seemed to make the reflux flare up again - apples, carrots (maybe?) and mangoes. We tried cheese yesterday just because I want to try him on dairy and he is really refluxy and hiccupy today. Went back to the doctor and got new meds - so will start trying them and see if they make a difference. His cot is still raised on a slant. He doesn't appear to be waking up choking as he did when he was younger, but I guess if he's even a bit uncomfortable then this might disturb him enough to not resettle by himself?
Sorry for another huge post!
