I really wouldn't stress yourself about it just yet! Enjoy her long naps atm I use our hammock for DD's day naps too (you're not strange LOL). I am thinking of transitioning her to her cot when she hits around 6 months of age, but we'll see how we go.

My sister had both of her bubs in a hammock for day naps and easily transitioned them to their cot when they were 6 months of age. My DS1 refused to sleep in his cot and stayed in his hammock until he was almost two. He then went straight into a toddler bed without any issues whatsoever .

I would honestly just wait until you think your DD is ready. To me it's not worth the stress atm when you might find she'll transition easily in a few months time

Just my opinion of course!
