M Cup vs. Mermaid Cup: Which The Mum Crew Kids Cup Is Right for Your Child?

The mermaid cup from The Mum Crew is a fan-favourite kids cup, but the m cup is giving it a serious run for its money — here's how to pick the right one.

The mermaid cup is one of the most searched kids cups in The Mum Crew range, and for good reason: it combines ocean-themed charm with practical, everyday drinkware. But if you’re torn between it and the m cup, you’re not alone. We’ve put both through real-world use to help you pick the right one for your child.

What Is the Mermaid Cup and Who Is It For?

The mermaid cup is a kids cup designed to delight younger children who love ocean, fantasy, or character themes. Think shimmery finishes, a mermaid straw, and a sealed lid that keeps spills to a minimum, the kind of cup that makes a child actually want to drink their water.

It sits within the broader spill-resistant category, similar in spirit to mermaid cups with lids you might spot in craft inspiration like this Mermaid Water Cup project. The Mum Crew’s version takes that aesthetic and pairs it with proper drinkware engineering.

Best suited for:

  • Toddlers and early primary-school children
  • Kids who respond to themed or character-driven products
  • Parents who want a cup that doubles as a motivation to stay hydrated
  • Families after a fun gift that still functions brilliantly day-to-day

What Is the M Cup and How Does It Compare?

The m cup takes a cleaner, more minimal approach. It’s the everyday workhorse of the range: less about the visual theme, more about reliable, no-fuss performance across years of use.

Where the mermaid cup leans into fun, the m cup leans into longevity. It’s the cup you reach for on school mornings, sports days, and road trips when you just need something that works.

Best suited for:

  • Older kids who’ve outgrown character cups
  • Parents who prefer neutral, versatile designs
  • Households that want a single cup style that grows with the child
  • Anyone after a genuinely robust spill proof cup

Spill-Proofing: How Do These Cups Actually Perform?

Both cups sit within The Mum Crew’s spill-resistant lineup, which also includes the spill proof sippy cup for very young children and the spill proof cup for general use. Here’s what matters when it comes to real leak prevention:

  • Lid seal quality: A tight-fitting lid is the first line of defence. Both the mermaid cup and m cup are designed with secure closures.
  • Straw fit: A straw that wobbles or pulls out easily is a spill waiting to happen. Look for a snug straw channel.
  • One-handed operation: Can your child open it themselves without flipping the whole thing? This matters more as kids get older.
  • Drop resilience: Kids drop cups constantly. Neither cup is indestructible, but both are built for everyday handling.

If you’re considering something more premium, the weesprout glass cups with lids & straws spill-resistant cups offer a glass construction option for families who prefer to avoid plastics entirely.

Material and Care Considerations

Most parents want to know: is this cup dishwasher safe, and what is it actually made of? Here’s our general guidance:

  • Check the product page for material specifics before buying, specs do vary between colourways and production runs.
  • Avoid abrasive scrubbers on any cup with a printed or foil finish, as this includes most themed cups like the mermaid cup tumbler style.
  • Straws need individual cleaning. A straw brush is a small purchase that extends the life of any lidded kids cup significantly.
  • Store lids off when not in use to prevent moisture build-up and odours.

For glass options, treat them as you would any glass drinkware: handle with care on hard floors, and check the lid seal regularly for wear.

How the Mermaid Cup Fits Into the Wider Range

The Mum Crew kids cups range is broader than just two options. Once you’ve landed on the mermaid cup or m cup, it’s worth knowing what else is available for siblings, gift sets, or replacements:

Each of these follows a similar spill-resistant philosophy, so you can mix and match across the range without worrying about wildly different quality levels.

Which Cup Should You Actually Buy?

If your child loves ocean themes or you’re buying for a younger child who needs a little encouragement to drink more water, the mermaid cup is the clear choice. It’s fun, functional, and fits neatly into the mermaid cup tumbler category that has become genuinely popular with kids and parents alike.

If you need something that will last through the chaotic middle years of childhood, travels well, and doesn’t require a theme to stay relevant, the m cup is the smarter long-term buy.

Either way, you can grab the 25% off code at our discount page before you order, it applies sitewide, so it works on whichever cup (or cups) you pick.
