@LondonPupMum we picked up our pup at the end of November and to be honest I found it very difficult until Christmas. It was such a shock to the system, but a lot of people cope much better than I did 
DH and I both had time off over Christmas and New Year and managed to get into a much better routine with naps and we were able to walk her just before Christmas was helped massively too. I am quite strict with our routine at the moment - mainly because HummusPup has terrible FOMO and would never nap outside of the crate. This helps me get work done from home, plan meetings etc, and makes the time we do spend together less stressful!
Hang in there because the first few weeks are tough but it gets better!
