Overview
MAM's Easy Start Anti-Colic+ is a 4.5 ounce wide neck baby bottle built around a self-sterilizing vent base designed to cut air intake during feeds. It suits parents combination feeding a young infant who wants a smaller starter-size bottle.
The wide neck shape is designed to mimic breastfeeding for an easier switch between breast and bottle, and the vented base sits underneath the nipple rather than requiring a separate insert. At 4.5 ounces it is sized for newborn portions rather than a full feed, so most parents pair it with MAM's larger sizes as the baby grows.
- 4.5 ounce capacity
- Wide neck, anti-colic vented base
- Rated for the baby age range
Who it's for
Suits parents introducing a bottle to a breastfed newborn who want an anti-colic vent without extra parts to lose or clean. Not the right size for a toddler already drinking a full bottle at each feed.
Pros and cons
- Vent built into base, no separate insert to lose
- Wide neck shape for breast-to-bottle switching
- Compact 4.5 oz size for newborn portions
- Small capacity means an early upgrade to a larger bottle
- Amazon listing has no seller description or attribute detail
Performance notes
The anti-colic venting is built into the base of the bottle rather than a removable straw, so there is one less part to align during assembly. MAM markets the base as self-sterilizing, meaning it is designed to be cleaned in the microwave without disassembly, though parents should still follow the included instructions for how long and how often.
