Make sure to focus your attention on your toddler if you've had a recent new baby. Make sure to have 1 on 1 time with her and make sure she knows she's your baby and you love her just as much as ever. Make sure you include her in helping out with baby, have her pick out baby's clothes for the day. Make her feel apart of the process. Unconditional love for your children is something I've embraced after reading an interview with Huffington and that was how she treated her children. With unconditional love. The adjustment is an adjustment not just for you and your wife, but for her as well. Don't forget to give her more love than ever.
