i got Walker (3.5 months) last week after having Troy (4 months) for a month and a half. i am not single and i have 5 skin kids ages 8, 5, 4, 1.5, 7 months... so my attention is already limited. getting Walker was a godsend because now Troy doesn't require all my attention cause she has a playmate. Walker is being crated to potty train so when hes not around Troy is with me.
