These sleepsuits are great value and the quality is superb. The side zip also makes them really easy to use.

Great baby grows. Come up small though. My baby was in 3-6 months at 7 weeks. 0-3 only lasted 7weeks.

Really great quality and ideal for nighttime as easy to change with the zip. They wash really well and look like new even after a few months. Fantastic buy.

Far too small

So disappointed with this purchase. I’m a big fan of the marks and Spencer zip up sleep suits and have bought every size since newborn. This style however is far too small, and I couldn’t zip the leg up on my 6 month old, 8kg baby

Nice sleepsuits but be aware of shrinking

Originally posted on marksandspencer.com (UK)

Good enough, bought both newborn and 1 month sizes and they both shrink in the wash (only at 30c) unfortunately, even without using the tumble dryer, so buy a size up.

I usually give 5 stars for M&S for quality and value, however one of the sleep suits stitching came undone at the crotch after just 1 wear,, it appears it wasn’t overlocked correctly. I was also disappointed to see they removed the fold over mits which the previous sizes had so not sure if that’s a cost saving exercise.

Practical but poor quality

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Practical but poor quality, 2 of the suits had not been overlocked properly causing multiple holes after just one wash. Another also had been stitched incorrectly so it did fully zip down as the bottom zipper. Would not purchase again.
