Not baby related but I'm still confused by "tea". Does tea refer to dinner or any meal? And what do you call actual tea?
Tea is a drink. Here "tea" is also like a mid afternoon snack/light meal usually involving the drink tea and cake. We call meals here Breakfast, Lunch and Diner... But some in the UK call them Breakfast, Dinner and Tea.
Like a Main Street in the centre of a town or community with most of the area's shops on. So like a little village might have the odd little corner shop dotted in but most would be on the high st. In bigger towns it is usually the main shopping centre of town (outdoors) which is referred to as the high st.
Oh got one. What's a council house? And what's a flat? I always assumed a flat was what we call an apartment - a building with several residences.
A council house if government owned and rented out at a lower cost than private renting. Those that receive benefits and or/do not work might have the cat of council housing rent paid for them... They used to be on council estates. Like set areas of town with just that type f housing in. So in a way a bit like how you describe the projects. But all kinda of families to there and now the councils tend to ensure a certain number of houses are allocated as council housing in each new build to give integration rather than set areas... To try and prevent that "council estate" mentality that gives some council areas a bad name.
Is this a sleepsack in the UK as well? I think I've heard them called something else around here.

Something else I've noticed (not really a word) is that so many women dress their baby girls in tights with shorts on top. I rarely see that where I am and have never seen a whole outfit in a store where you can buy shorts with matching tights. Doesn't it make it more difficult to do diaper changes? Just curious.
That's a grobag or sleeping bag.
The shorts with tights is one of my favourite looks here. But it is cold, skirts and dresses are a bit awkward with her crawling and rolling stuff and using cloth nappies means most jeans don't fit over her j-LO bootay haha. It's no more awkward than pulling down jeans I think, or even leggings... Just an extra layer.
Do you guys say ketchup or red sauce? I heard both when I was in the UK, is it a regional thing?
CATSUUUUP
Where I'm from pantyhose are like nylons or "stockings?", like tights with feet

. I just called them underwear, but panties are like girly underwear.
Pantyhose is the funniest word ever. That is all.
I know the thread kind of got away from baby stuff, but it's been bugging me lol - what's a babygrow? Is that what we call footie pajamas?
A baby grow is one of these... You can't see but it has feet on.

The same without feet and maybe with short sleeves and legs is a romper...like this.

Oh and on Sabrina the Teenage Witch (back in the day) she danced and sung a song that went "shake your whammy fanny, funky song, funky song. Shake your whammy fanny fu-UUUU-unky song".
That provided SOOO much humour here as basically she was singing "shake your fabulous vagina"
