Bedtime at 20+ mth

At 20+ mths, the toddler has much more to do before bedtime and also more verbal. Caught this over the weekend. Somehow it's been almost half a year since I last tried to use iMovie to make a clip sequence and certainly quite raw at it. Somehow, I simply couldn't add in the titles no matter what. Didn't recall it was that hard. So if there are any Mac user of this software, do let me know how to get it done as I haven't been able to do it even after reading the Help.
