No Problem at all. My DD was 18mths old when the twins were born so she didn't understand what was happening and as she was still a baby herself it took some adjusting to her having to wait until I was finished with the boys before I could deal with her, but she survived and now all 3 kids play together already.

It is hard to get your head around but I'll be happy to help with any tips/ideas to help you out and to hopefully save money on having to outlay on all the things you think you might need. PM me anytime you like.
