I'm sure this has been asked a million times and I've read FAQs but feel I need to ask specific advice on my particular situation.
DS is almost 4.5 months and is a short napper and pretty much always has been. I feel like I've tried watching and tweaking his A time and sleepy cues for such a long time and nothing seems to help. Sometimes he goes down beautifully for naps, just coos for a few mins, and sometimes we have a full on screaming fit which ends up with me either taking him out in the stroller or rocking him in the stroller inside just to ensure he gets some sleep and doesn't end up OT. Generally he wakes up happy and cooing although he'll be super tired and cranky a short time later. If he wakes up crying, I tend to leave him for 5 mins and he is able to resettle but only for another 10-15 mins or so. Very occasionally he'll sleep for 1hr15 but there seems to be no rhyme nor reason for this.
I am in the process of moving to full FF and have been doing so gradually so to prevent engorgement and it's working well. I have also recently moved him over to 4 hourly feeding. I haven't noticed any change in his sleep behaviour as a result of these changes. He has never slept well during the day.
We had to do some sleep training around 2.5 months old as he was waking 4-5 times a night and still only napping for 40-45 mins during the day so I was never able to catch up on any sleep. Please, no judgement here, I was beginning to go completely crazy from sleep deprivation. We tried a few different techniques (including BW shh/pat) but anything which involved us going in to him would just increase his crying so we would have to just leave him to cry. We mainly focussed on him getting to sleep independently at the start of the night and this pretty much solved our NW bar a 4.30am feeding. We introduced a dream feed at 10.30pm and this eliminated the 4.30am wake up. We've recently dropped the DF without any issue. We have done all of this in discussion with the pediatrician who is very happy with him. He's in 87% for height and 61% for weight (15lb 13oz at 4 month appt).
I have started a better nap routine which generally has helped him get to sleep for the morning nap (nappy change, into room with lights off, story, cuddle to lullabies, leave lullabies on) but is not always successful for the others. His room is never that dark. We live in the heart of a city with floor to ceiling windows. All sleep is in the crib unless otherwise stated. Unswaddled. No dummy - he has never taken it. No medical issues. When awake he is a very happy and very active baby. He's always on the move. Rolling inconsistently front to back.
His routine is generally EASASE.... with very little Y!

Then, he STTN which I am so thankful for as otherwise I'd be unable to cope.
I feel like I spend my entire day trying to get him to sleep. I'm out of ideas. Thanks in advance.
