Quoting Love Wedge +2:" So my son will be 4 months old next week. He's EBF. His dad lives about 2 hours away and wants to start ... [snip!] ... he goes away for the weekend. Or lose my supply because he's not BF on demand. Any other suggestions or tips would be helpful."
I know you say he wants to start overnight visits on weekends but frankly I'd say no. Most breastfed babies are feeding at night still at that age & if your body isn't used ot pumping like that, you won't get the sam eoutput & coudl even have issue swith plugs. i worked from 6 week sonward & when my 1st was about a year they started having me do some SHORT traveling - like overnight...and I have a terrible time with it. I couldn't get letdown, etc. My body was used to pumping EVERY day - yet when it had to rely on a pump for a full 24-36 hrs, it would not
fully empty or cooperate. No one could have been more surprised than me. I figured I was a "pro" at that point & knew all the ins & outs of pumping.
I understand why
dad would want this & why you want to cooperate, but I am not sure how practical it will end up being & once you agree to it & start, you may be stuck with it & I wouldn't want to take that chance frankly. Where I live, if you are allowing reasonable access to the child, most judges would not require
an overnight visit until age 3....especially when nursing. I also think it is very easy when you have a 4 month old to see an 8 month old as being so much older & have all sorts of ideas about how different your baby will be by then. It is true, baby will likely set up by then, have solid foods & maybe crawl (or in rare cases walk). But they are very much the same in other ways. Many still nurse just as often as they did at 4 months, even at night. That may sound discouraging if you have a baby that nurses every 2 hrs - but it's the truth.
If you do plan to go ahead with it - start pumping now & saving it. Like I said, getting letdown is hard when relying solely on a pump for days at a time, most times a baby overeats at the bottle so they burn through milk if the one giving the bottle is not cautious & so you may find yourself coming up short.
Here is info on how much baby is likely to need:
