How much more per nappy are Aldi Mamia night pants and plus sizes?

What does “plus” mean on a Mamia or Fred & Flo pack?

Plus is extra absorbency in the same size band, not a different legal size. Aldi’s size 6+ product page says it is “the same size nappy as the standard size nappy but with extra absorbency”. Tesco’s Fred & Flo size 4+ listing uses the same idea: “plus size — extra absorbency, same size, more absorbent”.

Which? lists Aldi sizes 1 to 6 “and there are also plus sizes for extra absorbency”, and prices plus rows as a step up from the plain size. Parents who grab a 6+ or 4+ thinking it is the ordinary jumbo are comparing two different £/each lines.

How much more were Mamia plus and night packs this week?

Figures below are Aldi’s Mamia brand page and product pages checked on 10 September 2026. Aldi states prices online may vary from prices in store. This is a same-week snapshot, not a permanent pence list.

The night-pants row is the large jump because the count is 15 and the product is built as overnight protection for older children, not as a daytime size 4–6 tape. Putting 31p next to 8p without saying that is a misleading gap.

Does Which? show the same plus-size step?

Which?’s Aldi versus Lidl pence table (same article) priced Aldi size 6 at 8p (60-pack) and size 6+ at 11p (46-pack), and size 5 at 7p versus 5+ at 8p. Those pack counts differ from this week’s Aldi pages (size 6+ is now a 50-pack on the live listing). The direction matches: plus is a higher £/each. The exact pence is not a rate to copy forward.

• Which? size 4 and 4+ both sat at 6p on that table (84-pack versus 78-pack) — a small or zero printed gap, like this week’s Mamia 4 / 4+.
• The step gets clearer at 5+ and 6+.
• Which? is not a night-pants price list. Use Aldi’s night-pants product page for that £/each.

What do Tesco plus packs look like next to Aldi?

Tesco groceries listings checked on 10 September 2026 showed Fred & Flo size 4 at £2.89 / 6p (48) and size 4+ at £2.89 / 7p (44). Jumbo size 4 was £4.99 / 6p (84); jumbo size 4+ was £4.99 / 6p (78). Same headline price, fewer nappies in the plus bag — that is how plus can cost more each without a higher pack price.

Asda Little Angels plus rows were not fetched live for this page. Use the Asda ticket’s £/each on the plus pack and compare it with the plain size in the same shop, same week. Which?’s size guide lists 4+ / 5+ / 6+ as higher weight bands with extra absorbency — still not a quality or overnight verdict.

How do I re-check plus versus night pence this week?

1. 1
   Stand in one size band Size 6 next to size 6+, or size 4 next to size 4+. Do not put night pants on that row.
2. 2
   Copy £/each from both tickets If the small shop omitted the unit price, divide pack price by the count on the bag.
3. 3
   Note the pack count Plus bags often hold fewer nappies at the same headline price. That is the usual source of the extra pence.
4. 4
   Keep night pants on a separate line Read the age or kg range on the night-pants pack (Aldi’s current listing is age 4–7, 17–30kg). That is not a daytime tape price.

This page does not say which pack to use overnight. Absorbency claims on the pack are the maker’s wording. Official NHS nappy-rash advice is still to change a wet or dirty nappy as soon as you can — extra absorbency is not a reason to stretch wear time.

In short, how much more are plus and night packs?

In shortOn Aldi’s 10 September 2026 listings, size 6+ was 11p against about 8p for size 6 jumbo, and night pants were 31p in a 15-pack. Plus means extra absorbency, not a new legal size. Night pants are a different product. Re-read this week’s £/each; do not copy these pence as a permanent rate.
