I am also worried about how to give DS1 attention when DH is at work and I am B/feeding.
DS2 has a bit of an unsettled tummy and I feel like I am always feeding him. Luckily DS1 only found it hard when I B/F at the beginning and doesn't try to pull DS2 off my boob any more.
ABC2 has been a lifesaver and although I know it is bad for them to watch too much t.v, I at least know he is learning a lot from some of the shows.

I have found though that my 2 yr old DS loves sticker books also and will sit there for quite a while picking and putting the stickers on and off the pages. I know it may sound a bit silly but we also got him a toy baby and when I am feeding DS2 he sometimes sits next to me and pretends to feed it. He really likes it and when he has had enough I get him to show me where the babies nose is or arm etc.
I know how hard it is but we are strong mothers!! Just do what you can and remember your an amazing mum!
