Find time for you to relax when they're in bed, but don't drink alcohol if it will compromise you dealing with an emergency and you're in sole charge. After lunch, have a quiet hour for baby to sleep, you to relax a bit and the two year old to look at books, do jigsaws with you or watch favourite TV programmes. Invite other young parents/grandparents to bring children to play - it's good to share, enjoy the children and be able to get food and refreshments without wondering how you'll keep an eye on them - so easy to miss meals when you're minding children. Structure the day and change toys over in the afternoon so they don't get bored, but always have favourite cuddly toy/blankie/dummy at hand just in case. Encourage mum and dad to keep showing your photo/Skype so the baby is also familiar with you beforehand. It's tiring looking after two children, but such fun. Good luck!
