We are moving from a one story to a two story house and I have no experience at all with baby gates. The house has two sets of stairs, each with a different situation at the top and bottom. DS is 12 mos old. We also have a 9 yr old, a dog and a cat if that makes a difference.

Here are the pictures of the top and bottom of each set of stairs. Can anyone offer advice as to what types of baby gates would work in each of these scenarios?
