I am still 10kg over my pre baby weight (which wasn't that flash to begin with). I really really need to do some exercise to shift the flab but I am having trouble finding any time to do it.

DH is at from from 7am-5.30pm. During the day I have DS and DD to look after. DS no longer has a day nap. DD sleeps for 45 minutes max at a time during the day and I use her naps to do the housework and spend some individual time with DS. When DH gets home there is a mad dash to get tea cooked, eaten, a family walk and bathtime done ready for DS to go to bed around 8. Then I hold/feed DD until she goes to sleep at around 9.30-10pm.

The only option I can think of is going for a walk during the day, but DD won't sleep in the pram so she gets grumpy and DS either walks (very slowly) or would fall asleep in the pram which creates a bedtime disaster.

I have no friends or family here that could watch them and there is no suitable childcare.

I feel like I am just making excuses. I am sure it is possible to look after two children and still fit in some exercise. How do you fit it into your day?
