Hi,

It sounds like you are doing it tough at the moment. It must be hard with your partner away and caring for a 8mnth old. but what you've got isn't a breastfeeding problem. When you are breastfeeding, and there are problems, the grass looks so green on the other side of the fence. The bottle is often held out by friends and family as a golden beacon that will solve all your problems. But, your child has plenty of milk and food - it's unlikely he's waking because he's hungry. Breastfeeding is easy on your body, and research demonstrates that mothers who breastfeed get more sleep than bottlefeeding mums.
I wonder, what can sustain you? What can you do to have your emotional and physical needs met? It's hard, but your partner will be home soon. If you do give a bottle of formula at night - of course you aren't doing the wrong thing, and you can still breastfeed, but it might not be the answer to problems
