8 mo old waking at 11 and crying all night

[KaiyasParents]

Our DD has been on EASY since day one with great success.  She had slept 7-6 am for months and we have taken it for granted.  4 nights ago she woke at 11 and started crying, we did the ussual shush pat which used to work.  She could not be consoled.  About 2 am we put her in bed with use as this worked once when she was sick.  She just played and laughed like she was on caffiene.  She slept a couple hours in the morning and was back on the routine all day.  We thought she was teething and did not worry about it.  After having four bouts of dihareha we took her to the doctor and he said she probably had a 48 hour bug going around, and to let it run it's course.

The next night she woke at the same time and could not be consoled.  She seemed gassy and finally fell asleep at 2 am but only while lying upright on my chest.

Last night same thing, she finally went to sleep at 3 am.

She has not deviated from the routine.  If it is a bug we are at 96 hours and why doesn't she act sour other than 11pm to 3 am?  Any suggestions to these night wakings?

Have you introduced any new foods which she has at a regular time of day or if she is BF have you eaten anything different at the same times of day?
What does her routine look like? Is she still having an upset tummy? Is this only overnight. Maybe this is a coincidence and her routine needs a tweak? we had dodgy belly for 3 weeks here which is apparently common for babes to take so long to fight it - even BF.

She has been trying new foods weekly but nothing new that is everyday.  She typically eats 6-8 ounces at 7, 11, 4, 7 pm.  Takes a bath and off to bed.

We have not changed her formula for 2-3 months.

Sorry I have been away and you haven't had ay other replies. Is she still having an upset tummy? What does her day routine look like?
