<p>I don't know about scheduling it, but I think that there are benefits to tummy time that are separate from those of being held/worn. When a baby is being held s/he doesn't get to practice rolling/crawling or pushing up with his/her arms. My older daughter HATED tummy time so I didn't do it very often. She learned to roll on schedule, but she was 9 months old before she began to crawl. FWIW she was held/carried constantly except when she was asleep... we couldn't really put her down.</p>

<p>When we do tummy time with Livia now she seems to tolerate it more if someone lies down on the floor and maintains eye contact with her and/or if we put her mirror or a visually striking (i.e. black and white) toy next to her. She also likes it if we put her on her stomach while she's on her changing table because it lets her see a lot more. </p>

<p>I've also been trying to let her spend some time each day sleeping on her stomach while stretched across my lap. It seems to both help with her reflux and give her a break from the time at night she spends sleeping, swaddled, on her back. (And also the time during the day that she sleeps in her papasan swing while I cook/clean/do things with her sister.) I really like wearing her (and it lets me get more done), but lately she's spitting up so much that it's less messy to just hold her when she's awake and put her down when she's asleep. I feel kind of guilty about this because her sister barely tolerated being put down for naps and as a result was held way more.</p>
