For babies, wait for food value 400-500,then give milk. Repeat 2 or 3 times this step. Then again wait same food value but give 2 milk. Repeat rhis. In all this time, babies wait outside of cyro. You don't need to collect milk for every hour. It is waste of time.
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
