I had dd 2 when dd1 was 25 months...not two under two but close enough.

My suggestions

Get the bedtime routine down. If you are thinking a big bed then do it now!! It took me over a month to settle Sara into a big bed..Thanks Lucy for those tips!!!!

Set up at good lunch time sleep routine too.

Have snacks available

DVD's a must

In the first few weeks ask a special family member to come over and do afternoon play and bath time for the toddler or take the baby whilst you do the routine and take time out with your first..I so wish I had someone to do this.

Bugger the house or set aside baby bonus money to have the house cleaned. My DH doesn't buy me flowers when I give birth he makes sure I come home to a clean house.

Get an answering machine.

Go with the flow...In times of stress (2 screaming babies) just think of a cool blue ocean and remember that tomorrow will be different.

When you need a break don't be afraid to call out for help!!!!!

All the best.....
