I have a 4yr old n a 11week old, ds1 turned 4 in Aug n baby born Nov, ds1 is pretty independent he can wait for things, play by himself, loves helping by putting nappies in bin, singing to his brother while I pop dinner on.
Ds1 is also at school so get daytime with ds2 although being up n ready for school run was a pain initially it's just part routine now, days seem shorter as have school run in afternoon too.
Sometimes I think ds1 misses out on my attention coz of bf n then lack sleep but he says he is ok and actually is happy doing craft, playing, watching tv.
I try to spend time with ds1 after school n in hols when ds2 naps so usual do a cooking activity like making pizza or flapjack or cakes as I like cooking as does he n we have a useful end product.
At weekends DH does alot with ds1 although now ds2 is almost 3mths he doesn't constantly feed we do a bit more family stuff.
Also when I go back to work we will have childcare all day for one n then around school for other we couldn't have afforded 2 in all day childcare.
