Slow Weight Gain & Jaundice · Tucson

Worried about your baby’s weight? We’ll get answers.

Slow gain and poor feeding are worrying, and they deserve a real medical evaluation rather than guesswork. We measure what your baby is actually taking in, find the cause, and build a plan to get growth back on track.

This is exactly what breastfeeding medicine is for. We can measure intake, examine your baby, and coordinate care, all in one visit, so you are not left wondering.

What we evaluate

We start by measuring milk transfer with a weighted feed, then look at the whole picture: latch and feeding efficiency, your supply, your baby’s exam and growth trend, and the medical causes that can affect intake or weight.

Sometimes the answer is a feeding adjustment. Sometimes it is a supply or transfer problem. Sometimes it points to something medical that needs treatment or coordination with your pediatrician. We will tell you which, and what to do about it.

How we help

  • A weighted feed to measure exactly how much milk your baby transfers
  • A medical exam and review of the growth curve and feeding history
  • Evaluation of the medical causes of poor intake
  • A clear feeding plan, with supplementation only when it is genuinely needed and a path back to the breast
  • Coordination with your pediatrician so everyone is working from the same plan
Caught early, slow weight gain is very manageable. Clinical terms like “failure to thrive” can sound alarming, but they simply mean a baby is not gaining as expected, and catching it early is exactly how we keep it from becoming a bigger problem. We track closely and stay with you until your baby is thriving.
It’s all connected. Your baby’s weight and your milk supply are two ends of the same loop. A tongue-tie or poor transfer can limit what your baby takes, which dials your supply down, and low supply can stall gain. We measure both and treat the whole loop, not one half of it.
What about jaundice? Slow weight gain and jaundice often show up together. A jaundiced, sleepy baby may feed less, and feeding less can slow weight gain, so the two can feed into each other. If jaundice needs its own care, we have a dedicated page for it. Jaundice & phototherapy →
When to seek care sooner: very few wet or dirty diapers, a baby who is hard to wake or feed, a sunken soft spot, or worsening jaundice. Seek urgent care right away.

Questions parents ask us

Does slow gain mean I have to switch to formula?

Usually not. Many causes are fixable. If supplementing is needed for a time, we build the plan to protect breastfeeding alongside it.

Will you work with my pediatrician?

Yes. We coordinate care and share findings so your baby’s providers are aligned.

How do you measure how much milk my baby gets?

A weighted feed: we weigh your baby before and after a feed on a sensitive scale to measure transfer directly. We repeat weighted feeds over several visits as we support you, work through any issues, and track progress until your baby is back on the right growth curve.

Is the visit covered by insurance?

Often, yes. We’re in-network with most major commercial plans, AHCCCS, and TRICARE. Because we often see families quickly, sometimes the same day or the next morning, and we offer Saturday visits, we can’t always confirm benefits before your visit, and we never let that delay care. These are medical visits, so your plan may apply a copay, coinsurance, or deductible. We’ll help you understand your coverage, and final benefit details are ultimately between you and your plan.

Stop wondering whether your baby is getting enough.
