Tummy Exercise

Since nowadays infants are not to sleep on their tummy (major cause of SIDS), they don't get to exercise their neck muscles as much as we did growing up in the 70s where sleeping on our tummy was the recommended position. We have been putting Joaquin on his tummy during his play time to help him exercise his neck muscle. Joaquin was not very comfortable the first few times on his tummy. This week he seems to become more comfortable with it. He can even lift his neck to change his face from facing right to facing left. Quite impressive for a 5-week-old (at least I think it is quite impressive for me). Although every time after he flips his head from left to right, he becomes very exhausted and would immediately demand us to put him on his back and he would just lie there resting for a couple of minutes with minimal movements. Today he did left to right and then right to left and he left a big pool of drool on the play mat. I guess we are going to be quite demanding parents...
