Hello, I had this same problem with all of my children...What doctors told me to do was give a little apple juice with water..but I found that a little harsh on a new born baby...yes your little is constipated, but also is normal to only have a bm once a day..its all about monitoring honestly...Im on my fourth pregnancy and is a custom now to these stressful situations, but its manageable...I started reading everything natural, and what I came across is the benefits of coconut oil...Coconut oil has hundreds of uses on our health, and body..And is essential to all of my baby regiments..Its has great benefits for baby skin, great for baby hair and cradle cap, and great for constipation...I use a q-tip and dip in coconut oil and gently insert to help move the bm...it gives the baby soo much relief..You dont have to do every single diaper change, but best when you notice the straining from baby...Also keep in mind, these are all learning times for newborn, and so even pushing a bm is a learning experience, it will take time for them to push on their own sometimes...And another great tip, keep yourself as stress free aa possible..newborns sense a stressful environment, and that can cause constipation as well...I hope everything works out.
