This response is provided based on the information you shared and should not be used as the sole source for making a decision. You should seek guidance from the chain of command, IG, JAG or other certified agencies before making any decisions. How you chose to use this information is totally up to you and is your sole responsibility.
The information you provided in my opinion would not qualify or be evidence for a separation under AR 600-20 Family Care Plan and/or AR 635-200 the Separation Regulation.
There is the alternative of child care and that is a reasonable solution.
If you or your wife fail to provide proper oversight and care for your child the commander could consider separating you with an involuntary family care plan separation. Taking this as a willful course of action could be considered a violation of the UCMJ as you have reasonable alternatives at your disposal
