My older two are 21 months apart and then with the littler one 18 months apart. I wouldnt have it any other way. It gets crazy at times. I have peace knowing though that they have each other and I will get to bask in the joy they are going through alot of the same teenage issues at the same time. I loved that I had my big sister when I got into HS. My little sister and I are 7 years apart and I didnt really learn to appreciate what an amazing person she was u ntil she got older.
You son may find a little jealousy towards new baby. I found out when my middle was 7 months old i was prego again. My first thought was ''oh no!'' Then as the two monkeys have gotten older they are the best of friends. They do everything together. So all the anxiety I had for my middle was settled when I realized I didnt take anything away from him. I gave him a friend, buddy and partner to have while Big bro is at school.
you will appreciate the closeness they will have together!!
Good luck and congrats!!
