Definately feed feed feed (when it comes to breastfeeding) at the beginning to make sure i establish a really good breastfeeding relationship asap! As i have had some issues with DD breastfeeding and have had to comp feed. Which i feel guilty about, but next time I will not stuff it up.
Also realising how important the whole "sleep" thing is, ie watching for tired signs and putting them down as soon as i realise they are tired.
