As a little kid, what words did you pronounce wrong?

It's a rainy day and - I'm bored. This isn't a game. It's just words that we thought we were saying correctly when we were little kids.
Here's two that I recall. Name some of yours.

Mirrow (mirror)
Parry Knife (Paring knife)

my name was barbara-joan, and I called myself, bee bee joe, (just a toddler then, according to my mom)

winnipeg was penneweg (from my daughter when she was little)

Shake-shake-shake
Shake-shake-shake
Shake your boo-bies
Shake your boo-bies

Shot through the arse and you're to blame
You give love a band aid

My daughters at three or five. Me? That was a long time ago

My dad used to flick his cig ashes into an asstree.

And on a related note, having grown up with an ocd clean freak, even I hadn't had to put up with waxing the ceiling, and couldn't for the life of me figure out who would need to do that or why (Puff the Magic dragon lyrics was my first exposure to the term 'sealing wax').

My nephew thought we were catching flies with a "sly slaughter".
At breakfast he drank "a pay goof" (apple juice)

Truck was one - Not hard to figure out.

Me to. All my "TR's" were F's so train was fain, try was fy, trampoline was fampoline and truck was.....

We lived two doors down from the fire hall and I always got really excited when I saw a fire truck and had to tell the world.

When I was 14, I worked as a cashier in a Shop Easy store. Little kids used to come in and ask to buy some "truckers". The first time a little kid asked me that, I didn't know what to say until my best friend actually leaned over and quietly told me they wanted to buy some suckers. They were not asking for truckers and as you said - not hard to figure out what they were asking for.

Forget "what words"; how about "what phonemes"!

I pronounced the hard "th" as "t", and the soft "th" as "d". I also pronounced some diphthongs as pure vowels, such as "e" instead of "ey" "o" instead of "ou" and such.
