Both of these phases are fairly normal (even though they make you want to tear your hair out)..
Right around this age their growth rate slows down quite a bit - so they eat less.
As long as the food choices you offer her are healthy, it's up to her how much she eats.
Offer milk to her after she eats so she doesn't fill up on it.
She'll have another growth spurt sooner or later and then she'll eat.
Our son also would not let me out of his sight (not even to use the bathroom).
He had to be right next to me.
For awhile just putting him down on the floor so I could handle something else would cause him to cry like his little heart was breaking.
Eventually he was happy just being able to see me from across a room.
And then he'd get too busy playing to want to follow me around the house as I was doing laundry or anything else.
He was about 4 when he finally eased up a bit.
