Acute Baby

I saw a design similar to this onesie when I was pregnant with Miss Baby J. We are kind of maker-type people (when we have the time). I put it on my list of things I want to make her, but I figured that I'd never get to it (much like updating this blog, which sat lonely for a few months while I was trying not to drown).

Anyways, I had a few days over winter break to create my own shirt. I dyed a white body suit purple and drew the design in Inkscape before John helped me convert it into a digital file that is compatible with an embroidering machine. It's fun to have unique, nerdy pieces, and "acute" model to wear them:

Inside of a breast pump

There, I've said it, "breast" is now on my blog. It's no secret that I work full time outside of the house. My breast pump provides me the opportunity to give my children milk during their first year. A few weeks ago, my older pump (~5 yrs old), which I currently use and keep at work, began acting up. It would oscillate and lose suction with each cycle. As an engineer, I wanted to find a fix.

For a week or two, just re-positioning the tube connection to the pump would keep it in long enough for my pumping session. Then that didn't work. I just needed the external pump cylinder (what I'll be referring to as the "suction piece") to stop moving in and out of the pump. If it was stationary, the suction would work just fine. In a pinch, I grabbed some scotch tape (the only tape I had handy) from my desk. That worked for a session or two. Then I added more and more tape until finally I remembered to bring it home to ask John for some duct tape (which we didn't have! I feel like we failed as mechanical engineers).

I explained the situation to John and that I just need the suction piece to stop moving and it works. John wanted to open it up. I was nervous, but it was well out of warranty and heck, we're engineers!

Voila! The inside of the pump. It's so pretty, and fairly basic!

We saw the plastic clips that held the casing surrounding the suction piece were broken and coming off, allowing the piece to move in a way that it wasn't supposed to. We needed something to wedge in there. Luckily, I hoard milk caps (for science!). With a hole cut out to fit the pump cylinder, a milk cap was wedged into the pump. The pump was closed and tested out. It worked!! It's been ok for a week now, and I hope it lasts for another 3 months. A penny solution is much better than buying a new pump!

Broken clips, like the one shown under the motherboard and our milk cap wedged in at the far right

On a customer service note, my original pump did die 9 months into J (5 yrs ago). It was still under the first year warranty, so I called and they overnighted me a new one (which is the one that broke this time)! I was (and still am) a very heavy pump user, and until I acquired a second pump, I was bike commuting with my pump, which probably gave it some extra shaking. All-in-all, I've been very satisfied with my breast pump.

Is there anything you recently took apart or reverse engineered to see how it works?

Are there any mommy tools that could be helped through better engineering and technology?

The Society of Women Engineers (SWE) had an innovation contest to redesign the breast pump. I'd love something quieter, less bulky/clunky, and more discrete!

Baby Science at Feeding Time

Simple science experiments that babies do on their own - and how you can embrace the science:

*Squish their food - How does that feel on your hands? Give them something else to squish with a different texture. How does that feel? How does it feel on your face? How does it feel on your hair? (It's inevitable, you'll have to hose them down anyways).

*Prefer one food - Give the baby a few different food items on the tray and watch him/her pick up the preferred items first. Once the preferred items are gone, watch which item disappears next. It's a form of sorting, the bin is just his/her mouth!

*Drop things - Where did it go? Did you hear it hit the ground? Give the item back to them (assuming you're ok with whatever condition the floor is in). Whoa, did it happen again? Was it the same? Then offer something different (i.e. plastic, wooden, metal spoons). Did that sound different? How about this sippy cup? Whoops, the lid fell off. Did you hear the water splash on the ground? (you'll have to wait a few minutes while I clean it up!)

Little Miss J is now 9 months! As you can probably tell by this post, we're well into the feeding craziness of babyhood. Oh, being a parent is fun!
