When to transition to toddler bed?

Elizabeth

So my son is 9 months and my husband is going into the airforce, while he’s in training and such I’ll be staying with my sister for a while and will only be able to bring what fits in my car. My son will be about a year old at that point, and I had planned on bringing the pack n play, but was wondering when people transitioned to a toddler bed? Or any other ideas? I can buy something when I’m at my sisters, I just can’t load up the regular crib with me as it’s too big and bulky.
