My mum loves all her grandkids - all 20+ of them! LOL. Ok, so she wouldnt look after them all at once, but she'd damn well try! She has been taking care of three under 5 recently as my poor sister has been in and our of hospital with some unknown viral infection (I believe today its pneumonia. Last week it was something else entirely - my dad has it too and so far for him its been pleurisy and a blood clot in the lung. Maybe one day they will work out what it is). It seems like a lot of work, but thats what the village does. I have a huge village - just none of them within 3 hours of me. I think you will find that you will cope amazingly well - and sometimes, just having that second person there with you for a visit is all you need for that day.

Then of course - in the end, this is yours and your DHs decision. I am sure your mum will still love to be a part of yours and your kids lives either way. Its what we mums do.
