Let to you friends
Both for you, and for the child, and for your husband important that you did not reach exhaustion and a depression.
If you have nobody to find to yourself in replacement, let your husband will sit with the child times a week until you go on a visit or to cinema.
Your husband too has to spend one or two evenings in a week outdoors.
The child does not need at once two listeners in the person of concerned parents.
Let to you friends come on a visit.
Remember, everything that helps you to keep composure that distracts you from concern on the child, eventually helps both the child, and all family.
