Sarah,
Huge hugs to you and well done for getting help for the reflux sweetie, I know it's bloody hard!!! Firstly you don't need to "pull yourself together", it's hard and you are having issues coping...we have a refluxer and I STILL go through patches where I don't cope, it is a whole different experience!!
OK, firstly if you don't have one I would invest in a sling or baby bjorn or something like that...we found our really good for our little refluxer. Seriously we would go for a pram walk then DH would spend the whole time carrying Dyllan and I would wheel the pram....We just COULD NOT put him down. If we were holding him, we couldn't sit down or he would start crying again....they just hurt so much, the poor little things.
I would imagine you have wedged the bed up and things like that? Feed well before naps and give your LO a very good burping, reflux babies have SO much wind and it can take hours to get it out of them. We also suffered with short naps, usually about 20 minutes, or he would be asleep in our arms but the minute we put him down semi-flat he would wake screaming again...I got to the point where I was shaking worrying about how I was going to settle him the next time as soon as he woke up.....
I know how you feel and I'm sending huge huge hugs to you.
What meds is your LO on now?
Ok as to your other daughter, it is hard sweetie, but they understand a LOT more than you realise. My step daughter has been absolutely AMAZING with Dyllan and very understanding. Admittedly my DH has done a lot with her to free up my time, but she has been very understanding too!!! Why don't you ask DH to look after your LO for an hour a week so you and your older daughter can go and do something together without bub? Maybe just a walk to the park or library, or a little trip to the shops to get an ice cream together??? Let her know that you are so proud of how she loves her little sister and you know it's hard because bub is taking a lot of time, explain to her about bubs condition and that it will be getting better soon....etc Talking to her will help you and it will help her, even if she doesn't understand all of it, including her will help her to feel a part of the situation
I didn't sleep train my bub until he was 11 months old (we didn't medicate until 10 months, huge mistake) so I get the limited YOU time....the way I would start is to shush pat your DD in your arms until she is asleep or nearly asleep...place her into the cot (warm with a hot water bottle first if it's cold where you are) and either put firm pressure on her shoulder and hip (lie on the side if you are comfortable doing that) with your hands, so she knows you are still there, shush pat if it comforts her more......Keep doing this each time, but gradually put her in the cot earlier and earlier, so she is going down semi awake. If she wakes at 30 mins, go in as soon as you can (don't wait....well I found with our LO if I waited I would have NO chance of getting him back to sleep as soon as he got wound up the reflux would get really bad) and pick her up, give her a back rub and try again. If it doesn't work put her in the sling and try again next time....
Your bubs sleep cycles will extend naturally as she gets older and so the wakes will be further apart. Does she sleep in the car seat? If you are having a bad nap day, take all of you out, bub may have a rest in the car and it means you and older DD can get out of the house and get some fresh air all together...
Hugs to you sweetheart, I feel for you, this will get better...hang in there and chat any time you need to, I'm here
