I think it could be the sleep too,was gonna say the same thing.
When i got home with Tabs i didnt realise babies need that much sleep!
she was screaming the house down mainly in the evenings between 6-9 ish until she was so exhausted she conked out. Some days did it all day too though.
Obviously we were thinking its her reflux or maybe its colic etc it wasnt until i read a book which gave an example of a good sleep pattern for night time that it said whatever time they get up in the morning they should be there abouts settled if not asleep by that time in the evening so sure enough tabs gets up between 6-7am (save this week when it went to pot lol) so now i bath her at 6pm and fed at 7pm then sure enough with some rocking she nods off......sometimes just half an hour then a little more milk then nods off for the night but mostly for the night until a night feed which time depends. Hope this is making sense.
What time is Charlie settling down for?
I also read that a baby who sleeps between 7pm and 10pm actually sleeps better at night time.
Also babies are usally tired after being awake for anywhere from an hour after being awake....Tabs awake times limit is usually an hour and a half in the mornings an hour ish at lunchtimes and sometimes awake for 2 hours in the afternoon,i mean thats the time she starts getting fretful and gives off the tired signals then i take her somewhere quiet ish (hard in this house) and rock her gently over my shoulder.....she will then stare for about 5 mins(which is part of the sleeping process) then nods off.
She only naps for half hours at a time.
I really hope im making sense as i really feel for you as my past with Tabs sounds very similar to you. once we realised what bedtime she wanted things SOSOSOSOSO improved DRASTICALLY!
I also now write everything down that she does and when,feeds,how long it took and how much etc,sleeps how long and when etc and chart it so i can see a whole week on one page with coloured columns lol i know im pedantic but i assure you it works really well and i can now see her tired patterns etc and that helps me to know when to get her off.
Sorry if some of this is irrelevant but just trying to get everything over at once lol
also when he gets fretful can you hear his reflux? if he was severely crying you could probably hear it from across the room or a few feet....its like a clunking glugging noise gluk gluk gluk thats the only way i can describe it.........if it is you seriously need to get the domperidone and ranitidine as that would prevent it sooooooo much.....tabs has grown 2lb since her last dosage was upped and sure enough this week her reflux has been 100% more noticeable as she has been screaming the house down so i got the dose upped.
