My DS is 2 and I couldn't imagine leaving him overnight. He still needs me in the night. Does your husband understand about the biological bond between a baby and mother. It took my DH a little while to understand it. He used to carry DS in a sling when he was newborn and I used to get all anxious, wanting to hold MY baby! And when he was around his parents and they criticised my 'constant feeding' we would argue because he was even slower to give me the baby back. I look back on it now and I should have just told everyone to go to hell as I am the MUMMY and my instincts were right just like a mummy lion, gorilla, cat etc would rip apart anyone who tried to take away her babies for even a minute!! OUr society is not really good with the mother and baby bond unfortunately.
