To help our toddler, I bought him a present 'from' the new baby which he opened when I brought the baby home. It helped avoid him feeling a bit left out of all the fuss over the new baby. It was a little house with people which he loved (and kept him a bit entertained, which was useful!)
My other tip is to make up a small box of books, stickers and toys that you only get out when feeding the baby to keep the toddler occupied. Also, I tried to involve them as much as possible in 'helping' with baby, eg helping choose a babygro for baby, fetching nappies etc.
One thing I noticed was that my toddler wanted to use all the baby items, he wanted to lie on the playmat, get in the cot, sit in the bouncy chair, which I humoured a bit, but drew the line at him getting in the sling
.
I'm not going to lie, the first few weeks are hard and exhausting but you'll get through it. Accept any help you can and do the minimum housework required!
Good luck with the birth and congratulations
