Just found out I'm pregnant and my youngest will be around 2.5 when baby is born. She's pretty good at the moment - listens, will hold hands when asked, can share and take turns and understands a lot of what I say etc but I appreciate all this could change at any point! I think 2.5 yrs will be a lovely gap when they're 3 and 5 for example, but honestly how tough is at first?
