I too remember the huge rush of possessive love you have for a Grandchild (its a cliche but its true). However, you do have to bide your time and bite your tongue as offering to help can be seen as many things by the new parents, especially those who are a liitle less than confident.
Off the top of my head MILs and even Mums offering to help can be seen as any or all of the following.
Interfereing, with the implication that you are just not up to the job. Bossy and possesive. Nosey - checking out how you are coping with THEIR grandchild. Critical - you are doing it all wrong. ETC ETC.
As Flowersof thewest suggests, its far better to offer to help in a non-baby way. A bit of housework, shopping or similar. Dont forget the new Mum will be awash with hormones, lack of sleep and just general bemusement at the task in hand. Give them a bit of time and I am sure you will be soon able to get your ration of cuddles.
