Daughter aged 3 can't pronounce R's properly

[SnackBitch2020]

My 3 (almost 4) year old daughter has really clear speech and a good vocabulary, but can't pronounce her "r's" properly. The R sound comes out as W e.g. she says tweat instead of treat.

Is this something that she will likely grow out of?

Thanks!

DD (4.5) is the same with R (pronounced W) and L (pronounced W or Y). I'm sure she'll grow out of it soon enough but I'll secretly be a bit sad when she does, because it is really cute.

My dc were funny instead of saying baby wipe it would be a series of vowels
sounds 'eaipe', lootube -youtube and some others that she has sadly left behind as they were cute but I can't remember them.
