What age did your LO start interacting and enjoying the floor gyms? I think my DS likes his, but doesn't quite have the skills yet to grab for anything, but he is only 5 weeks. Mainly he looks and wiggles, but no crying for a good 10-15 minutes before he wants to get picked up again!
Re: activity mats/ floor gyms
She really started liking it around 5 weeks. Now at almost 7 she yells and smiles at her animals.
