Hello!
I've just been to my local Tesco's where they currently have a baby event on. I've been able to stock up on all my favourite baby essentials and they have some great deals on Pampers, Huggies and own brand nappies. I was able to pick up newborn nappies (which have been rebranded to Tesco Loves Baby) for £1.71 which I thought was pretty good.
Highly recommend checking it out!
