# Day 80: Standing on your lap

> Legs that push, a head that holds steadier each week, and a bounce on your lap that is play, not practice. Plus the one thing about your own body to raise at the postpartum visit.

This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Hold your baby upright on your lap this week and you may feel something new: a push. Today is about the legs, and about one question you owe your own body.

## Heart

Held upright on your lap, your baby may enjoy bearing a little weight and bouncing, and by month three kicks get stronger ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-Birth-to-Three-Months.aspx)). Holding the head steady when you hold them is a 4-month milestone ([CDC](https://www.cdc.gov/act-early/milestones/4-months.html)), a list of skills at least 75% of babies show by that age ([Zubler et al., 2022](https://pubmed.ncbi.nlm.nih.gov/35132439/)); a head that wobbles and then catches itself is the practice version.

## Head

This isn't the stepping reflex coming back. That one usually fades around 2 months ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/newborn-reflexes.aspx)). What you're feeling now is a push your baby chooses, and the lesson is the same one the kicking mobile taught 3-month-olds in the lab: my actions make things happen ([Rovee-Collier et al., 1980](https://pubmed.ncbi.nlm.nih.gov/7375924/)). Push, and the grown-up bounces. The AAP describes supported "standing" on your lap as a fun way to play, not an exercise; it hasn't been studied, and your baby isn't behind if their legs fold ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-Birth-to-Three-Months.aspx)).

## Body

Two safety lines for a bouncing game. Keep it gentle, and never shake a baby: it's never safe to shake, throw, hit, slam, or jerk a baby, and if you feel yourself losing control, put your baby in a safe place like the crib, leave the room for 10 to 15 minutes, and call someone ([AAP](https://www.healthychildren.org/English/safety-prevention/at-home/Pages/Abusive-Head-Trauma-Shaken-Baby-Syndrome.aspx)). And the lap beats the bouncer seat: the AAP advises against leaving babies in bouncers, where they get less chance to practice using their muscles ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-Birth-to-Three-Months.aspx)).

## Try today

### Supported lap bounce

- **Time:** 1 to 2 minutes
- **From the guide:** [Supported lap bounce](https://chorevia.com/learn/2-months#supported-lap-bounce)

1. Sit your baby facing you and hold them firmly under the arms, supporting the head as needed.
2. Let their feet touch your thighs and allow gentle bounces if they push.
3. Add a bounce rhyme to the rhythm, and stop the song when they stop pushing.
4. Stop when they get tired.

**Make it work:** Keep it gentle, and never shake a baby ([AAP](https://www.healthychildren.org/English/safety-prevention/at-home/Pages/Abusive-Head-Trauma-Shaken-Baby-Syndrome.aspx)). The bounce comes from their push, not your arms.

## Watch for

- **Normal:** legs that fold one day and push the next. **Call your pediatrician right away** if your baby seems especially floppy, or has shaking of the whole body ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-Birth-to-Three-Months.aspx)).
- **Normal:** a head that wobbles and steadies with practice ([CDC](https://www.cdc.gov/act-early/milestones/4-months.html)). **Bring it up with your pediatrician, don't wait,** if your baby uses only one hand or one side of the body ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Movement-Birth-to-Three-Months.aspx)).
- **Normal:** a baby who wants to be held upright all evening. **Call within a day** if you're worn out from the crying ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Crying+Baby+-+Before+3+Months+Old)).
- **Normal:** knowing this baby better than anyone alive. **Call anyway** if your baby just doesn't seem right to you. Trust your instincts; eighty days have made them good ([Lurie Children's](https://www.luriechildrens.org/en/blog/when-to-call-the-pediatrician-for-your-newborn/)).

## For you

Your core and pelvic floor. If your postpartum visit hasn't happened yet, ACOG's deadline is 12 weeks after birth, and recovery is on that visit's agenda by design ([ACOG, 2018](https://pubmed.ncbi.nlm.nih.gov/29683911/)). Put "my core and pelvic floor" first on the list, in those words, so it gets asked about and not skipped. If the visit already happened and nobody raised it, call and ask; it's a normal question.

After a C-section, the lifting limit, nothing heavier than your baby for the first 6 to 8 weeks, has ended for most by now, and most regular activities come back in 4 to 8 weeks ([MedlinePlus](https://medlineplus.gov/ency/patientinstructions/000624.htm)). "Allowed" and "ready" aren't the same word. Lap bounces are fine; the heavy stroller up the stairs can still be someone else's.

If you're the partner: hold the baby through her appointment, in the room or in the waiting area, so she can answer the questions about herself.
