How am I going to be able to bf with a toddler around?

Its a little tough th first couple of days out of hospital but they get used to it very quickly. Just have something on hand to give to your child when they ask.. Such as a muesli bar and drink of water. Give it when they ask not before you feed

How can I keep DD occupied and happy whilst attending to nb?

Same as above really. Just talk to them and tell them what you are doing. I found with Jacob sometimes I had to leave him while I attended to Isaac. I think the NB copes quite well with that. they tend to fit in with the family routine more easily

How can I get all the house works done?(I am a house tidy freak)

Can't help you here. i just do the basics and then DH and I get stuck in once a week to get it done

How am I ever going to get out of the house for appointments?

Same as above. I am lucky to have Dh home every 4 days for 4 days so we have appointments around his days off. but I still have to get my eldest to school on time on my own when he is at worl and to be honest you just get it done. I get out of bed a bit earlier when DH isn't home and have my morn coffee ect then tend to the kids and we usually leave the house right on time if not earlier

How do I establish a good workable routine?

Just relax and let things flow. try and relax about a set routine. get used to being a mummy of 2 then work out what works for you. I used to cook meals early and reheat later and bath time ect i did it at midday (for NB)

ow am I going to get dinner on the table?

Thats tough at first and sometimes we ran late. once again I am lucky to have a DH who is an ex chef and is home alot.. but there are 2 days each week he isn't home at dinner time. I had simple meals that took next to no time to cook.. or as i said above cooked in the middle of the day and reheated later. I found giving a late afternoon snack was good especially if I was running late. The thing i found the hardest was when the baby would be crying for a feed and i would be in the middle of cooking dinner and my toddler wanted his dinner. it was stressful but I just turned off dinner. gave toddler a small snack fed the baby then got back into it....

Not sure if I helped any. but thats what we used to do and hopefully can do again this time.
