DivorcedAndDelighted would you not agree, that the tantrums are concerning in themselves, regardless of whether the mother is BFing?
And that people (the public but also professionals) very often tend to jump to blaming BFing in the first instance, for all sorts of problems, or even for things that aren't even problems.
Baby sleeping too little? Mothers are told to try cutting out BFing. Baby sleeping too much? Try cutting out BFing. Baby on the large side? Try cutting out BFing. Baby small? Try cutting out BFing. Mother at the end of her tether? Try cutting out BFing.
Similar happens to mothers of DC with SEN. The DC's behaviours caused by their SEN are often blamed on parenting for a long time before any support with SEN is suggested / forthcoming.
Surely, if you are so familiar with BFing support, you'd agree that we don't have enough information here to form a decent picture of what's going on? The OP has focused on BFing as the ex has, and she's obviously been made to feel she's doing something wrong here so there's plenty of guilt involved.
(I noticed that the OP hasn't said if she WANTS to wean or not, but she has said it is her plan.)
But, she's outlined that she's ALREADY cutting down on BFing, but had a spanner in the works by a temporary situation involving a poorly relative, which has meant she's had to bedshare for a few weeks.
She also outlined how she is trying to deal with the trantums and it was all standard stuff.
Are you saying you think the OP should carry on trying to night wean while bedsharing on a temporary basis? Fuck that for a laugh! Weaning while bedsharing is tough if you're the one with the boobs, with no boobless person to back you up! Waiting a few short weeks for her DC to be back in their own bed before continuing weaning sounds sensible to me.
Why are you joining this chorus of people bashing the OP over the head with a stick about ending BFing, instead of being a bit more sensitive and evidence-based?
Perhaps trying to find out if there are other issue at play here, for example, rather than blaming the BFing on the basis of such scant information? How do you know the tantrums aren't down to SEN or trauma, for example? Would cutting out BFing help if these were the cause? I doubt it.
