My ds is only 10 months but I'm thinking of number 2. Can't decide whether it would be better to have another one now and get the sleepless nights over with or whether I should wait so that I can focus on ds1. Would love to know other opinions? Is it a nightmare of new baby waking toddler and vise versa? My Mum definately thinks we should wait until ds is at least 3yrs. My brother and I are 3 1/2 years apart but aren't really that close. Can't decide!!!
