re the swaddling I would do what works for you atm. At this age we did swaddle day and night as DD had such restless legs but it is totally up to you, if it does not help then don't do it.
What I would say is that it will drive you crazy putting him down for this many sleeps a day and basically being in a dark room so make sure that at least one nap is out and about, in the sling, car or push chair. YOU need to get out and think of yourself too, he is still very young and as long as you are trying to put him down in his cot once or twice a day you are doing great
I am a bit confused on the first day as it seems from your EASY that he slept 7.50-9.30am but he went back down at 10am? That was a great nap so he could have handled the full A time.
The average at this age is 1.20-1.30 but if he did a good one on 1.10 then stick with that for the first nap and then try to add 10 mins on for the next A time so maybe 1.20. A lot of lo's like a shorter A time as their first one.
Also - this is nothing you are doing wrong hun, babies have to learn how to sleep. Some people are lucky and their lo's are angel sleepers from the get go but most are not. Make sure you get out and about as this will keep you happy and tbh if they short nap in their cot then you might as well be out and about having some fun or fresh air. There will always be more naps
