I'm now in my 60's & my son is 28. I was widowed when I was pg & brought him up alone. As the only adult in the house it meant that I had to take him with me when I visited the loo as I couldn't/wouldn't leave him alone even for 5 minutes. This also meant that he witnessed me using sanitary towels (I felt that using tampons in front of him might be a step too far & left them for when he wasn't around). So, in answer to his questions I used to say that everything was all right & I was using a 'special plaster' because mummy's tummies get ready to make a baby every month, but there needs to be a daddy in order for that to happen and, since there was no daddy, mummy's tummy had to get rid of everything that it had made ready for the baby and the mummy had to use a 'special plaster' eg: sanitary towel. I then made a joke about us not wanting a baby wanting their nappy to be changed & keeping us awake at night with their crying. Wondering how other mums deal with this?
