What Chester Needs after hatching

Day 1 With Chester

Day 2 With Chester

Day 3 With Chester

Chester was really starting to grow big now. He was now in stage

thirty. You could really start to see the changes in his body now.

He was starting to develop blood vessels inside his body. You

could also see his heart now. This is a big jump for him. Pretty

soon he will actually have blood going through him.

Day 4 With Chester

The next day with Chester was a very interesting one. He

started having blood going through his body. I was very happy

to see this. I could now see more life in his body. As a parent I

was very excited to see this. He was now in stage 36 of

development. I was so excited for him to hatch soon!

Day 5 With Chester

This was the best day of my life Chester had finally hatched! I had

so many plans for him now. The first thing we were going to go do

was get him a new bigger bowl. Sydney was going to take him

since it was his choice. Once we got to the store he told her that he

didn’t care how big the bowl was as long as he was with Sydney

and I.
