I have 4 dc under 6.5: 2 dds, 6.5 and 4.5, and 2 ds, 2yrs and 4 months. Both girls have had a term at nursery a while ago, but I firmly believe in HE, for myriad socio/psychological/educational/moral reasons which would take far too long to detail...
Unfortunately, my personality (levels of patience/noise tolerance/physical strength & energy etc) means I actually find it really hard to remain calm and 'nice' to my children, particularly when I have been up every two hours in the night breast-feeding the 4-month old, and the two-year old is having a full-on hysterical tantrum on the other side of the toilet door, because I have DARED to lock him out for 2 mins...
Whilst - in theory - I would love to spend lots of time playing/reading with my elder DDs, the reality is that almost all the time the toddler is around is spent with him trying to destroy any game they might be playing, or grabbing any toy that anyone else shows any interest in - and then I just shout a lot, and collapse on the couch when he finally has his nap, with no energy left for the girls....
Sorry this is long; I know there are those of you out there who HE larger families than mine, yet somehow remain sane and good-humoured (most of the time...we're all human!) So if anyone has any practical advice/moral support/encouragement, throw it my way!
