It really does sound like a dramtic improvement Julie - which really does make me think the prevacid has helped as well. It sounds similar to what Megan has done on the Zantac (not as great mind - I think she may need prevacid too
).
Babies do cry - that is what they do for any which reason - if you feel a lot of the crying is related to OT then you are likely right. And I guess what we are saying is that untreated reflux is what is causing your bad nights, and then often leading in to OT during the day. I must say that is what makes my Megan scream really - OT - but that is after have all those 30 min naps where she has woken due to pain. I know it is discomfort as I hear her regurgitating, or passing wind, but these episodes make her fussy or squeal rather than cry.
I see what you are thinking about sleeping peacefully after a big feed - but he is sleeping elevated in the swing. Could very well be totally different in you plopped him in the crib.
I'm pretty sure I have said it before - but I really do believe that a babies personality has a huge impact on their reflux behaviour. So if Caleb is an angel he will not be affected in the same way as a touchy iyswim?
Looks like your LO needs a short first A time then. That is handy to know, isn't it? So routine wise the question is how to keep on track during the day and avoid unsettled evenings.
Just to mention one more thing about sleep deprivation and PPD - yes they are very strongly linked - of course they are - but you have to bear in mind that it may be months before you get consistant good sleep. And even then you may find yourself dealing with a preschooler waking with nightmares, or whatever. I know your toddler sleeps more than mine does, but I think it is in some ways risky to decide that my whole emotional well being and mental health depends on me getting something that I know I often will not be able to have because I have children to care for. So sometimes you have to try and tackle both issues together - sure work on your LOs routine and HIS sleep - but also work on ways to help you that are not dependent on what someone else does. I'm not sure I'm explaining myself well here - but I hope you see what I mean.
I am not a very patient person either, and that is something I have to work very hard at with young children around.
