Love the name lol.. Well my Peeka(lol) he was going up and down the stairs since about 9 weeks with no probs he is now 9 months and does it with ease. Our new baby Daisy is 12 weeks and she can mad dash up them but if she is higher than the 3rd stair she won't come down them. They are determined though and eventually will go down it only took Peeka 2 days to master them |
