  • 6-8 Sleepsuits – Easy for day and night wear.
  • 6-10 Bodysuits – Layering essentials for all seasons.
  • 2-3 Cardigans or Jackets – Ideal for outdoor strolls and cooler days.

From everyday essentials, to special keepsake outfits, our baby clothing range at Bumbles and Boo is designed with both practicality and charm in mind.

Every baby grows at their own pace, and some little ones will move through sizes faster than others. This guide is designed to help you find the perfect fit.

  • Prem - premature sizing is determined by the baby's weight
  • Newborn -  normally fits for the first 0-6 weeks
  • 0-3 months - too big for newborns, from around 4-6 weeks old until 3 months
  • 3-6 months - as the size name suggests
  • 6-9 months - as the size name suggests
  • 9-12 months - as the size name suggests
  • 12-18 months - Also try age 1-2 clothes at this time
  • 18-24 months - this is the biggest size in months, move on to age 2-3 after this size

We stock lots of well known brands, ensuring every gift is of the highest quality. These include: Mary Meyer for soft toys, Neal’s Yard for skincare & Steiff for teddy bears. We are also committed to using sustainable, eco friendly and organic options where possible which can be seen across the store.
