Reflux and a 15 month old?

My nearly 16 month old was diagnosed with reflux at 3 months and was on losec till she was 13 months old. We went through a rough patch of about 5 days when I weaned her off losec but apart from that she's been really good. I can still see the milk coming back up her throat and hear her swallowing it back down sometimes but it doesn't seem to be causing her any pain. But....she has developed into a really terrible sleeper during the day. The last 3-4 weeks or so have been a disaster in terms of day sleeps - she's gone from 2 sleeps of an hour to an hour and a half, down to one sleep of between 10 and 50 minutes. She is so tired her eyes are practically hanging out of her head. And she now seems windy a lot of the time, burping mainly but also a reasonable amount of farting too. I am wondering if the reflux is still bothering her and I talked to the doctor but she said that it doesn't sound like DD is in any pain so it probably wouldn't be the reflux causing the day sleep issues. She said I could put her back on losec if I thought it would help but only gave me a 2 month supply. I don't want to put DD back on losec only to have to wean her back off again but....I am a bit concerned that maybe the fluid coming back up is disturbing her. She still occasionally spills and on Saturday she lost all her breakfast and her bottle on a car trip (she doesn't normally get car sick). I guess I am just after opinions on whether babies who have had reflux can get worse again after being better for ages.

Cooper a silent refluxer, if you can see milk coming up & hear it I'd put her back on it. We missed 2 doses & I had a miserable little boy for a good week afterwards.

We couldn't see that he was in any pain, I guess the dummy helped a lot.

With us the night sleeps go & he's sleeps most of the day. So she's probably sleeping at night cause she's so exhausted.

What dose have you got for her? I was put on 10mcg & was told if that didn't help I could give him 20mcg. We've stayed on the 10 mcg dose so maybe if she's on a 20 you could give her a half dose to start with? I dunno though, you'd probably need to talk through with your dr about that.
