20m speaking well but cant pronounce "L"

[talilac]

DD1 (20m) is speaking really well, but for some reason can't say "L", she substitutes it with a "Y" - ie Lala is yaya. Shes got no other language problems, has a good vocab, is putting sentences together etc.

Is this a usual thing? Will she just pick it up at some point or is there something I can do to help?

Any advice much appreciated.

my dd can say 'l' but not 'y'!

My ds was about 14 months old when he started to say "clock". Sadly he couldn't pronounce "l" at that point either - cue lots of sniggers when out and about with ds pointing and shouting "cock" every so often!
