Well I would consider today a sort of success LOL.
He had a 1hr 20min nap in the AM, which is typical for him...no issues there. I managed to get him to sleep by 2:30pm, though it took a lot of support from me (patting his back etc.), and he stayed asleep (YAY!) until my stupid dog starting barking for absolutely no reason and woke him up at 3:40pm. I made a sad attempt to get him back to sleep, but we wasn't responding easily and I figured there wasn't much of a point, so just got him up. I think had the dog not barked that he would have stayed asleep until 4pm or so. I am just going to aim for a 7pm BT tonight.
He seems to either have every teething symptom under the sun, or...he is slightly under the weather which is obviously not helping naps or our nights. He's congested today and his cheeks are bright pink - I gave him some ibprophen before his PM nap and put some vicks in his humidifier. The IB seems to have helped a bit.
In any case, I'll try to keep the same routine tomorrow - 9:45 AM nap, 2:30 PM nap.
