Three months already. We now spend a great majority of our time doing just about anything to get this child to laugh. She does do it. Inconsistently. Randomly. Sparingly. And because we've had a taste, we are never satisfied. Sisay will spend long minutes trying to weedle a little giggle out of her, and if he succeeds, will spend longer minutes repeating the same noise/movement/utter ridiculousness until both Samaya and I are very extremely unimpressed. And then I take a turn and repeat the process. Lots of effort for little effect. And completely worth it.
