MOTHER DISCONNECTING FROM BABY

Hi,
My older sister is 39 Yrs old and has a 3 yr old daughter. She is a single parent and starting dating someone who lives 6 hours away. I fear my sister is disconnecting from her daughter and wants to date and live freely without the responsibilities of being a parent. She works full time and goes away with her boyfriend practically every weekend while my other sisters or grandma babysits for her. She also recently left on a 10 day vacation WITH HER BF without her daughter so basically she sees her daughter after work enough to feed, bathe her and put her to bed and weekends shes gone.

The 3 yr old is showing signs of insecurity and abandonment issues. She never lets her mother out of her sight and asks every hour if her mom is coming to pick her up whether it be from daycare or where ever she is at the time. She is angry and cries and doesn't know why but i think she misses her mom.

Recently my sister asked me to babysit this weekend so she can go off with her BF and this is the 3rd weekend in a row she wouldn't be spending with her daughter. I'm also pregnant and have severe nausea so obviously not ideal.
IS THIS NORMAL SINGLE MOTHER BEHAVIOUR? should I confront her that she's being a selfish mom and she's abandoning her child? DO I STOP BABYSITTING HER DAUGHTER?  I'm not a parent yet so not sure how to handle this but I can't see how this is ok??.


ANY THOUGHTS PLEASE.......

Hi,
I feel this is very selfish behavior by your sister. She most definatley needs a life because she is a single mom but she needs to realize that her child is her first priority and the boyfriend needs to be on the back burner. I wonder if she doesnt realize the damage she really is causing her child very selfish. As for you babysitting I would do what you feel is right but remember as long as your neice is with you she is safe and happy what happens if you or no family member will babysit what is going to happen to that child then and will your sister leave her wiht anyone just to go out? I hope this helps have a nice day. Good luck with your baby they are a blessing I have 3:)

Hi,
Her child should come first. This relationship may not work out & where will she be then. These effects on her daughter can be lasting. She has to make a choice. But this also says a lot about her bf. Why does he allow her to be away from her daughter so much? I'll be praying for you guys.
