So... I currently have two under two. Ds is a very, VERY active 21 month old and ds is 6weeks. It is not as hard as I anticipated, but it's HARD! The lack of sleep is the culprit. I am assuming it can only get easier as DS starts to sleep better? Some friends have said otherwise which is scaring me... As once younger one is mobile you have two to run around after. I don't see how that can be harder than being up from 4am after interrupged sleep, but then what do I know really?! I'm new to all this ??
