Anyway, I would steer away from feeding-related gifts
Agreed, feeding is a very personal choice and can be very emotive for some if it can’t/won’t work or you they are being made to feel that their choice is wrong.
Frozen meals have been suggested lots, I hope you know whether they have a large freezer or not!
Sleep related gifts might be a good shout. We made do with neither a Ewan the Sheep (we got a white noise app for a spare phone) nor a SleepyHead type thing, buy have heard good/ok things about both. The issue is that they can seem like a lot of money to gamble for tight-fisted new parents!
Small, practical gifts, maybe a couple of pairs of sock-ons or mocc style slippers?
A card book? The Emma Dodd ones are very sweet, as is Ten Little Fingers or – a current favourite for our 16-month old.
