I never did the converntional tummy time but rather "tummy on mummy" time. I would slouch back on the couch and have my boys on my chest. Naturally they would try to list their heads to look at me and eventually paw at my face, but being on me have them a comfy feeling and it was a lovely way to have cuddles AND get their necks strong as well. Also, when they got tired and slumped forward, landlong on my chest/shoulder was softer for them than the floor.

I used to do this whenever I watched telly or just felt like hanging out with my babies.
