Most parents expect teething to bring fussiness and disrupted sleep. What catches many off guard is how much it can also affect feeding. A baby who has been nursing or taking a bottle comfortably for months may suddenly pull away mid-feed, chew on the teat, or seem reluctant to feed at all.
Changes in feeding behaviour during teething are common and, in most cases, temporary. Understanding what is happening tends to make the disruption easier to manage for both parent and baby.
How Teething Affects Breastfeeding
Many mums find that breastfeeding when their baby is teething looks quite different from the weeks before, even when nothing about the feed itself has changed. When your baby's gums are swollen and tender, latching can feel uncomfortable in ways that are hard to anticipate. Some babies pull away from the breast mid-feed, fuss more than usual, or take shorter feeds. Others nurse more frequently, drawn to the breast as much for comfort and pressure relief as for milk.
Biting is another common response. The pressure of biting against swollen gums brings temporary relief, and it is a reflex rather than a habit. Gentle redirection tends to work well: unlatching calmly, offering a teether, and returning to the feed once the urge has passed.
The feeding pattern during teething can also start to resemble cluster feeding behaviour, with your little one wanting to nurse more often and for shorter stretches than usual. Meeting those cues, rather than pushing for longer sessions, usually helps both of you get through the disruption with less friction.
How Teething Affects Bottle Feeding
The sucking action during bottle feeding creates pressure on the gums, which can make feeds uncomfortable enough that your baby pulls off, chews on the teat, or takes less milk than usual. Some babies refuse the bottle altogether during teething, particularly when gum soreness is at its peak, and the refusal can feel sudden if feeding has been straightforward until now.
Teat material can make a genuine difference during this phase. Softer, more flexible teats place less pressure on tender gums and tend to make the feed more tolerable when soreness is high. This is worth considering when reviewing your baby's bottles, as not all teats are made from materials that offer the same level of softness and flexibility. Hegen's PPSU range is designed with this kind of comfort in mind, which is part of why many parents find them easier to work with during the more tender teething stretches.
Tips to Make Feeding More Comfortable During Teething
A few practical adjustments tend to ease the disruption without overhauling your baby's entire feeding routine:
- Offer a chilled, not frozen, teether or clean, damp cloth for a few minutes before a feed to take the edge off gum soreness before your baby latches or takes the bottle.
- Keep feeds calm and unhurried; a tense or rushed environment tends to heighten rather than settle discomfort.
- If your baby is on solids, cool purees or soft chilled foods can soothe gums while still providing nutrition during a feeding dip.
- Offer more frequent, shorter feeds rather than pushing through longer sessions when your little one is uncomfortable.
- Stay consistent with feeding routines to give your baby a sense of predictability during an unsettling phase.
When to Be Concerned About Feeding During Teething
A temporary dip in appetite during teething is expected. Most babies take less milk or food for a few days and return to their usual intake once the tooth has come through.
Signs worth raising with your paediatrician:
- Fewer wet nappies than usual for your baby's age
- Lethargy or unusual listlessness beyond typical teething fussiness
- Consistent refusal to feed lasting more than a few days
- Noticeable weight loss or failure to gain weight as expected
If you are breastfeeding and concerned about supply or latch changes during teething, a lactation consultant can help you assess what is happening and adjust your approach if needed.
Teething Is a Phase, Not a Permanent Shift
Teething-related feeding disruptions are temporary. They can feel significant when they occur, particularly if feeding has been straightforward until now, but most babies come through the early teeth without lasting changes to their feeding.
Patience and flexibility go a long way during this milestone. Meeting your baby where they are, adjusting the pace and frequency of feeds, and keeping the environment calm tends to make the disruption shorter and less stressful for both of you.
Hegen's range of baby bottles, feeding sets, and accessories is designed to adapt across every stage of your baby's growth. For families navigating bottle feeding issues during teething, the right teat softness and bottle design can make a quiet but meaningful difference from the first tooth onward.
