14 months old regression

Just when I think I got her pattern down pat,  she changed it again.

Three weeks ago  it all begun by Alexis slept in her high chair at 6:30pm, twice exactly at 6:30pm, and then the subsequent two nights she slept at 10pm.  

Since then she was waking up SO frequently at night, every 1-2 hours.  It drives me crazy, triggered my arthritis pain,  it made me feel anxious with frequent, random and 'unpredictable' pain all over my body.  My baby is also much more clingy during the day, I have to breastfeed her to calm her down.

Leap 9 - Walking, talking a lot more
Eight teeth coming out
Ate a lot less solids
Ezcema flares

Since the two combo, I felt like we are back to newborn stage

Breastfeed more frequenly during the day - Before, she feeds first thing in early morning (say 4am) then morning (say 10am) then not until 7-8pm - so 2 times during the day.  Now she breastfeeds 4am 7am 10am, 1pm, 4pm, 7pm, so 4-5 times during the day.  She often cries in pain. Her solid intake has reduced so I wonder which comes first, but its not good.

Breastfeed more frequently at night - Before, every three hours. Now every one-two hours. She often cries in pain. Even sometimes breastfeed don't settle her. 

Eat less solid - I am seriously starting to worry that she does not eat enough. She even rejected her rice (come on she is such an asian baby who loves her rice), rejected her meat sometimes, and don't eat as much for breakfast. She completely reject vegetables. She still loves yoghurt though. 

Now can only be put to bed by boobs only - Before she can sleep 30% of the time being pat pat on bed, 30% of the time being held, and 40% of the time by boobs. But now its 100% by boobs.  I am worried of her dependency on boobs.
