This will probably sound terrible to begin with but I promise it's not how it sounds first off!
Firstly, I would not breastfeed. I breastfed both my Children and loved the fact that I could and could do it for a long time - one till they were 15 months and the 2nd till they were 1. However it took alot out of me and as I suffered severe PND I felt very pressured and relied on and it was not very good for my state of mind. It's for this reason that I would bottle feed.
Secondly, I would continue working - again for my state of mind.
Thirdly, I would be more disciplined with routines. With my 2 Children I was very relaxed on their routines as I really didn't know what to do to create or enforce one. Now that they are older we have a strict routine and I would continue this onto the next baby if there ever is another one!
I have considered MCN's but I don't know I could commit to it... I don't know!
One thing I would NOT do is introduce solids too early! I didn't give my kids solids until between 6-8 months when they were ready (not spitting it straight back out) It astounds me how young some people start their babies on solids. I overheard a Mum at school the other day who has a 5 month old who is on 3 meals a day and 1 half bottle, and that they started the baby on solids at 2 months old. She was explaining how the baby eats exactly what the parents eat and yeah even though they spit it out, or throw it up straight afterwards, the baby will learn that it needs food not bottles... My jaw was on the freaking floor. If I was to have another baby, I would not follow this kind of trend, I would wait until Bub is ready. I don't mean to offend anyone with what I've written above, I just couldn't believe a 5 month old was already eating everything the parents were.
