I have a lot of experience bringing memories up from early life. At first I blew a few threads by getting excited I had remembered something and leaving the remembering part too soon.
Now I sit and reach a calm point in meditation first. Then I remember either a specific place of item from early childhood and I sit in that place and remember all the times I visited there, or relive the life of an item like my first wagon. When I reach the memory of seeing it for the first time, I carefully replay everything I have remembered back, sometimes a dozen or so times. This brings other memories around the place or wagon to mind and I can choose to follow those.
Eventually, before I stop remembering, I place markers on the memories I just u covered and return another day to see if there is more. Family have been great for this, I have two older brothers who have clear memories from the day I came home from the hospital. So early incidents where no one was watching the baby can be verified.
