We have a changing table sans the contoured pad. We have the pad it came with then a towel down. Our secondary station has a wool puddle pad and a towel over it then a rolled up crib bumper around it. It's not secure, but since you shouldn't leave a baby alone on a table anyway...

I've seen the straps used with changing babies that can roll and some of them scream when they realize they're strapped in. It all depends on the child.

I've seen the pads used for tummy time and sleep aids.

I think what you do will depend on what works for your situation.

Something you may want to look into being diagnosed for (or ruling out) if Polycystic Ovarian Syndrome (PCOS) I had very irregular cycles as a teen. I went on birth control- when I went off of it I didn't get any period for about 6 months. Then they came irregularly again and with added pain. It took a specialist, blood work, ultrasounds and such to figure out I have PCOS- which is the leading cause of fertility issues.

The good news- with treatment with Metformin 80% of women conceive in 6 months. After 6 months most Dr's put you on fertility drugs. I was very lucky in that it took 2 months to conceive my DD who is now 8 wks old.

Just something you may want to look into.

Good luck!
