I didn't, and TBH I wasn't really looking for any gift at that time. I guess I would have ABSOLUTELY loved if DH was so moved by the event that he just wanted to do something to commemorate the event or to say thank you, but both times I got some flowers that came with an explanation of how they weren't very good and what little effort he went to in getting them. Yeah thanks.
Interestingly after DD2 was born I was doing some thankyou gifts (home cooked slices) for my OB and Midwife and a couple others and DH said 'where is my thank you food' (as a joke). So I did make him a thank you gift (to continue the joke) but afterwards I did wonder where the heck my 'thank you for throwing up for 8 months and getting that which was once inside outside' present was LOL
