Hi hun,
I don't have any advice for you really, but I know how scary it is to have neurologists involved, and not have any answers. My son had a stroke at 7 weeks and so far it's very much "wait and see", which is so hard. Why do they consider your DS to be delayed in his gross motor milestones if you don't mind me asking? What has helped me is to try and take control where I can and do something positive. Neurologically, baby massage is something positive you can be doing. I'm doing a lot of singing, talking and just general play and interaction, like round and round the garden etc. Also baby sensory and stimulation with textures like messy play etc. I don't know if/how much this will help my DS or yours, but feeling like I'm doing something staves off the feeling of helplessness I get sometimes. 2 months on and I do feel more positive, but I still have bad moments/days. My health visitor has recommended I get some counselling which I have requested. I guess what I'm saying is give yourself time, I hope you get some better news going forward. Big hugs xxx
