Hi - I am so sorry to hear what you're going through. We have just gone through and are still going through the same thing (except for the odor issue). I have a nine month old little girl who, at her 6 month checkup was not sitting well with support or rolling back to tummy. Her head was lagging when lifted by her hands from lying flat. She was "floppy". Our ped recommended a ped neuro also. I got another ped's opinion and he recommended a developmental pediatrician instead b/c in his words ped neuros don't primarily focus on "developmental delay". B/c I got several encouragements in that direction that's what we're doing. It's hard to get an appt though. We are going to see Amy Pakula with the Marcus Institute on the 16th of May. The biggest thing I would recommend is that you get connected with the Babies Can't Wait program ###-###-####). It is a federally mandated program through the Easter Seals. They will come evaluate your child and design an IN-HOME (or in day-care if that's where your child is) physical/occupational/speech therapy program specifically for your child's needs (the cost to you is whatever your insurance company covers and a small co-pay or absolutely free if your insurance company doesn't cover anything). We have been doing therapy for two months now and our sweet Alexandra is now sitting beautifully and rolling both ways all over the place and is pushing up in an attempt to crawl. Her delays are no longer there and the therapist (who we love!) says we're just about ready to discontinue therapy b/c she's on track now and has no other milestones she needs to reach.
The reason I didn't go with the ped neuro was that I didn't want to put her through zillions of blood tests or MRIs with sedation, etc. if she was just a late bloomer and needed a little more time! I praise God that we went that route!! I don't know about your little one but the best encouragement I received was that it takes late babies and early babies to develop an average. My first born rolled both ways at 4.5 months and crawled at 7. He was early and she was late and my middle child was right in between them. So there you have it. It's an average.
I hope you'll be encouraged by this. If you have any more questions about our journey, feel free to contact me at ###-###-####. My name is K. and I would be happy to help you. I'll be praying for you and Levi.
P.S. If you decide to go the neuro route, the best in Atlanta from what I've heard is Child Neurology of Atlanta ###-###-####) with Dr. Edward Goldstein being the absolute best and Dr. Howard Schub being great too. I have had several friends whose children have had neurological disorders as well as a couple of friends who work for Children's Healthcare who rave about them.
P.P.S. My older two - boys - are 15 months apart. It gets easier!! You won't always feel like you've been hit by a train. Mine are now four and three and LOVE each other and play beautifully together.
