My niece

So my two year old niece and I have grown so close since I've been pregnant and ever since her mother started two jobs I've been the one watching her from morning to night. But I have no problem with that I love them both. My problem is that I'm sad that I'm not going to be so close to her anymore. My baby is going to take up to much attention and I feel bad. This little girl gives me so much love and holds me at night. It's just sad because soon I'm not going to be holding her as much or give her the much affection she gives me 🙁
