Tummy Time

According to any baby book I have read, Gabriel should be doing twenty minutes of tummy time a day.
He isn't that interested in it and won't put much effort into lifting his head, instead he appears content to just lay there and eat the floor.
I then had a genius idea to use his breastfeeding pillow to help prop him up in the hopes it might be easier for him...
No such luck, as you can see he just patiently remained in the same position I left him in waiting for me to pick him back up!
Oh and he ate the pillow instead of the floor!
