This is really important, especially with bottle fed babies.  If you are just propping your baby up with the bottle in their mouth this will increase the possibility of them choking.

Also if you are putting your baby to bed with a bottle, this could increase the chances of ear infections later on in their life.

The best reason that I can think of to hold your baby while have their bottle, is the bonding time that you get.  As your baby looks into your eyes, you know that they are thanking you just by the way the look at you.  They are priceless times that you can’t get back, so why not hold them a little bit longer!
