DD woke up every couple hours last night. It's exhausting, especially since I'm pregnant.
She's 16mos.

Now, she's always been a pretty good sleeper and when she wakes at night we just give her a bottle and a snuggle in our bed and then put her back in the cot and she falls straight back to sleep.

But, she had 400ml over last night and that's way too much. She was soaking wet this morning, even though we changed her at 2am.
She will generally scream until she gets a bottle in the night, I really want to break the habit.

Any ideas?
Do we just reduce the bottle size?

I don't know what to do.
I don't want her waking during the night every time the baby cries and not being able to settle her without giving her milk.

ETA: She won't co sleep, either. She gets hyper and likes to tickle us.
