I've just had a little one too, and have a toddler... The sling and nursing basket haven't worked for me. But everyone swears by them :) Will sling baby when he's a bit bigger :)
What has worked :
*Making toddlers lunch night before or in the morning so it's ready to go at lunch time
*I have had a small glass of wine most evening :) so... It has helped... The wind down when toddler is sleeping is important to me :)
*A few choc biscuits (seriously have everyone take her some biscuits when they go to the house. They will get eaten, and won't require extra attention like flowers do!)
*My toddler has a playroom. This works a treat. It was just his birthday, so there are some new favourite toys in there for him to play with. He goes in for about 20 minutes or so once or twice a day. I can shower or feed newborn,- huge help! :)
*A swing/ playmat/ bouncer/ Moses basket - I have all four and regularly pop newborn in for a few minutes time with the toddler.
*Also having a "routine" in place for toddler helps me. .... I try to stick to his routine, and fit in babies needs (eat/ sleep / diaper) in between as they're more simple. I find knowing that my day is divided into kind of 2 shifts (morning before nap and afternoon after nap) helps me make it through :) if all goes to pot, we watch a Disney movie or go for a walk.
*Also getting hubby to get toddler up/ dressed and fed in am helps me as I then have time to feed newborn right at start of day...
*Also been making sure to take my vitamins. I had stopped but have felt noticeably better since starting again.
*I'm also not worried about major housework right now (I had a csection and so can't anyway), so I just try to do a bit of laundry and feed everyone. Hubby does dishes... We will catch up on proper cleaning when I'm feeling better and more used to having 2 to look after all the time.
Will post more if I think of any :)
