Hi @Elley Tipton,
I feel that if you are newly certified in Infant, I would wait until the Toddler one is available. However, this is really up to you on what you would prefer. If you ended up enrolling in Infan/Toddler, you would be certified in both at the same time which may be easier in the long run. It's completely up to you! Let me know if you have any other questions!
Best,
Rachel
