Here are some ways Dad can be a good assistance to the new mommy and baby. This is a great way for Dad to build his confidence too as a provider and caregiver. This will also help him and the baby bond during their new relationship.

1. Remember that babies aren't really breakable. Don't be afraid to hold yours. If you are unsure of the proper way to hold the baby be sure to ask at the hospital prior to leaving and/or relatives or friends.
2. If you are feeling left out talk to your partner about it. Chances are it's not on purpose. Mom has a lot on her mind and she is exhausted, even if she appears to be full of 'energy'. Be sure to 'jump in' and help or ask.
3. New moms often have emotional ups and downs that are not predictable. Be supportive and offer a listening ear when possible. Learn the warning signs of postpartum depression and seek help if the situation is heading out of control. If new mom gives you answer of 'nothing is wrong' when you ask be sure to inquire a little more. Often women can hold back and want you to really inquire rather than start an empty conversation. Don't take what she discusses personally, she is probably just needing to talk to an adult and express herself. Remember she is talking to you because she trust and loves you.
4. Support her with breastfeeding. Tell her that you're proud of her and protect her from well meaning but negative comments about breastfeeding. Take a breastfeeding class during the prenatal period if possible. This helps to show you that there are many other men involved in breastfeeding classes and it is cool. Breastfeeding is best and you two have to be a team to give your child the best nutrition.
5. Help with the other children (if applicable) or household. Remind mom to let the house go and to focus on her recovery and the new baby. In order for her to concentrate you will have to have the 'path' picked up so she won't be reminded of clutter. Try to make things cozy and comfortable.
6. New dads can also experience the blues or postpartum depression. Much in your life has changed and its important to realize this and get help if you need it as well. Afterall you have to be available for help at the house in addition to carrying on with your job. It often helps to talk to your spouse daily about your new life together and discuss the positives of this new life together. Also reflect on how the two of you met fell in love and made this new baby.
7. Remember that the only thing you can't do is breastfeed. You can change diapers, soothe a crying baby, carry the baby, play with the baby, anything the baby needs done. But you can bottle feed breast milk and make your own bonding time with the baby. Even if the baby only takes a little from the bottle it is shared time together.
8. If you need help ask for it. Know who to call in your area for help and support whether it be a doctor or midwife, a postpartum doula, lactation consultant, or the local babysitter. If you need assistance with finding child care or funding for child care contact the Child Aware program for assistance. They can guide you to your local Child Care Resources and assist you with a list of local facilities. Phone: 1800-424-2246 for assistance.
9. Mom is going to need extra sleep and care while her body recovers. Get up with the baby when you can. Bring the baby to her in the middle of the night if possible. If you must go back to work check in with her during the day. Perhaps surprise her with some healthy take out food or fresh flowers. Be patient when you get home. She may approach you with help requests (a list) or ask lots of favors. Keep in mind she is not being bossy she is just trying to finish the task for the day. If you really want to get in good, just give her back and neck rubs. This area is extremely tired after holding a baby all day.
10. Remember that adding a new baby to the mix is always going to stir your life up a bit, even if it's not your first baby. Learning to live with another human being takes time. Give yourself a break if you need it as well.
Schedule days that each of you can 'get out' and do a normal adult outting with friends or alone. It will refresh both of you when you get back together.
