Wow, parenting is so tough, I have 2 boys- they fed till they were 4.5 and 2.5 when I got pregnant again and my milk dried up early on. The night feeding can be so exhausting - the wakings/ constant hunger and that’s just for you! It certainly means I become shouty mummy as well!
The funny part of breast feeding is there is pressure to start, maintain but then no support around stopping or how to stop with older babies who need boobs for food and comfort, once they are at that point convincing them they don’t want boob is hard work.
firstly he is 18 months, he is so little.
if you stop feeding at night he might sleep through or you might just be stuck with him waking up and then having no magic solution.
like your son my oldest was a terrible eater, until he was about 2.5 and he started to eat, but I remember at 18 months he would just want boob, I would get home from work and he would be superglued, weekends would be boob all the time if we weren’t actively doing something, which is hard when you just want to stop and relax at times.
If you want to stop feeding then you probably need to own it. My husband was useless so it was on me and it is hard. I tried saying no/ back rubs/ offering something else but it was hard and I worked full time so would give up. Especially when he would complain that he was being kept up by them being upset. They accepted no boob at night when there was no milk and they knew there was no milk.
if you want to continue then magnesium supplements are supposed to help and Epsom salt baths. I haven’t ever organised myself to get them but I can say multivitamins really help me. I had success at this age with countdowns when I was overwhelmed. After a few weeks they would pop off before I finished and the counting helps to focus you as well. I’ve also found allowing the uninterrupted boob can really help, I used to go out, come back after lunch and just curl up on the sofa, put a film on , snacks, drinks and just embrace it. Mine would frequently nod off and then just enjoy the nap or have my own one there.
it sounds like you could do with some more support, if you choose to continue breast feeding maybe try a la leche local meet up, they have mums feeding all ages and it can be really great to be with other mums on their feeding journeys for that support. I’ve met some great people and we don’t just chat about boobs.
tantrums- it really is age and just him expressing a view but it is hard work! Boobs here can be your friend if you want. There are countless times I’ve just offered boob to stop the tantrum. Now mine are not feeding I offer hugs, they just connect with me differently but it still offers a quick result. otherwise preparation is key, plan for the day, being out to run off energy . Snacks- all the snacks and drinks to prevent tantrums related to hunger/thirst, activities at home, keeping each activity to 30 mins unless he wants more. For my own sanity we did a variety, build the train track, painting, singing blah blah blah.
i hope you are able to find a way to get the balance back whatever you choose to do. Good luck!
