recommendation on deciding baby crib model and nappy changing area

Hi mummies, I am an FTM currently in week 29. I am renting a 2 bedroom HDB flat and planning on putting baby crib in my room, a bit of space constraint. I am still confused what baby crib to buy. Some sellers recommend buying models that can cater until the baby are toddlers or 4-5yo. Or should I buy bedside crib instead? What about changing area, I dont think I can have a dedicated changing area. So what are the pros and cons? #Needadvice #firsttimemom
