I need advice I’m struggling and want to have another baby

I have a 13 month old and I’d like to try and have another baby but I don’t want to until my daughter will sleep fully in her own bed. She sleeps in the pack n play beside my bed, I put her in it and she sleeps for a few hours in there but around 12 she wakes up and only wants to hop in our bed and sleep for the rest of the night. I can’t have that when I decide to try for another. That would be too hard.

I need advice on how to break this habit?! I really need some help. I don’t know what to do😞
