I guess it all depends on how old bub is? You could maybe put her in bed awake and sit by her side and comfort her that way. And just talk soothingly to her.

What are you useing (if anything) for the silent reflux? Isaac (now 3) had something similar and we used a thickener. You can also use it while breastfeeding but you have to give a little bit before a feed. I expressed and added it to his bottles.

Night waking will just depend on how old your bub is
