Ok, I have taught Hannah how to sit, lay down, roll over, and stay. I work with her everyday for atleast a half an hour but it just seems like lately she forgets. She's almost 8 months old and we have been working on these commands for five months on a daily basis. Also she won't stay until I release her. I'll always put her in a down stay and she'll sit and after like ten seconds will just leave on her own accord. Am I expecting too much from her? All I want is for her to remain laying for 30 seconds without having to remind her. How can I refresh her memory on her commands and help her learn to stay in one position longer?
