My DD, who is almost 2, is now obsessed with Charlie and Lola. When she sees the television she shouts 'Lola' and turns it on, even though it's only on for 10 minutes a day. When it actually does come on she runs and tells everybody 'LOLA'.
Previously she would get very excited about In The Night Garden, but she's lost a lot of interest in that now.
She likes wildlife programmes as well, but won't do what she's done now, which is sit on my lap staring Charlie and Lola for three consecutive episodes on youtube, saying 'More' after each one.
