I love how you define our generation of mothers as the "me time" generation. Are you aware of the fact that more mothers co sleeping (or sharing rooms with their children and breastfeeding their children than the women of your generation? Where exactly is the "me time" in all this? And where you do you get the "this generation of mothers" part? There are 45 year old moms on MDC that are TTC #1 and 21 year old moms of three here. The generational gaps are huge. There is no such thing as "this generation of mothers."
Thank you for mentioning that. I'm one of the older moms here and I am technically a baby boomer, so my generation is more likely to comprise of grandmothers than first time moms.
That being said, I'm with the majority here that if this is what the OP needs, then go for it. I say this as a WOH mom who extended breastfed my DD until she self-weaned at three. At 18 months, my DD would have been fine for a night or two and my only concern would have been my own supply (which wasn't an issue since I pumped at work anyway). My breastfeeding relationship certainly didn't end when I went to work, in fact it created a better connection with DD. She learned to have great relationships with others, but through breastfeeding, our relationship was something special.
