Hi Nancy
Facebook is a conundrum at the best of times. Facebook is a social network first and foremost so people go there to get to know what there friends and family are up to. Its evolving for business users but you need to be careful.
Posting several times a day and just selling your product can feel a bit like spamming. You want to engage your fans. Talk to them, make conversation with them. Ask questions...
When people respond to you with comments reply to those comments get the conversation going and build a rapport. People on facebook buy from people they like and trust. So this is important.
Facebook doesnt work on like anymore it works on something called
Edgerbank rating and from what i have been told The more people that comment or like your photo or post the more facebook thinks people are intrested in your posts and the more people it shows your posts to.
If youare stuck and you posts and being picked up try promoting and use this to get things rolling. Also there is a great page called 'Hike those likes America' which has great tips on how to help get seen on facebook. I will post the link below.
keep at it, people will start responding. Keep it regular though.
