so sorry about your ex. but i commend you for thinking about and caring so much about your daughter considering where you are and your situation. regarding the bed, why not just sleep with her. since my kid was a baby, we sleep together in our big bed until today and she is already 2years old. it's fun to enjoy every moment with your baby. for me, she is still too young to be on her own bed. for the car seats, just choose the one that is appropriate for her age, i'm sure they are all the same. for toys, choose the ones that can develop her speech or communication skills, my daughter has this toy with buttons that has all the letters and numbers in it, so when pressed, the letter or number is said aloud. potty training usually starts around 2yrs or later but this is very challenging as you need to have a lot of patience and your kid must also know how to recognize if she wants to go already. there are still a lot of things that will still come your way, just face it calmly and do not stress yourself, enjoy being a parent and not just only a dad, if you know what i mean. hope this helps!
