Dear Allysa,

Do you have a 30C kit? With a small child, you won't regret buying one, and you'll use it often.

I would put your puls. 6X in water--a disposable cup--and I'd give it to the baby, stirring before each dose, every 15 minutes until you see a change. If it's a change for the worse, stop the remedy altogether. If it's a change for the better, give as needed.

One dose of the 30C might have been sufficient to cure--especially at the beginning of the cold.
Try to start treating at the beginning next time.
There are some remedies that are specially designed for the start of something, especially if there's a sudden onset, like Aconite and Belladonna. Oscillococcinum at the first sign of a cold or flu often knocks it right out.
