I have my top three:

My 'fertile mind' feeding pillow. good for B/F and formula fed bubs as it means that mum doesnt have to strain her arms etc holding bub while feeding. and as newborns they fit on it totally and can lay really comfy while feeding.

A HUGE box of newborn huggies disposables. we were using cloth but DD was tiny and couldnt really fit at that stage and it was great to use this in the first weeks.

A book called 'baby love' by robin barker. i didnt realise at the time how handy it was for the late night panic moments where you need someone to tell you that it is completely normal to not know what the heck is going on...

they were my three faves and as such now gift them at showers...
