I confess I haven't had time to read every response.But DIL123s early comment about a MIL who has made little effort ,or had little involvement until the baby comes along really resonates with my DDS experience with her partner's mum.For several years they,as a couple ,were lucky if she even got back to them if they phoned .Rarely invited for a meal.DDs partner virtually lived with our family on and off when home on leave from the forces, before they had their own house, as there' wasn't room for him', despite a large house. His mum has been totally focused on her younger son from her 2nd marriage, whom she has smothered,and DDs partner has barely been acknowledged .Now obviously I don't know the full history of their relationship from way back when.
But still when our DD had the baby I have stressed that even though she and I are close,and live nearby,to not leave the other grandma out.It's her grandchild too.And our DD has really tried,and is still trying for her DHs sake as much as anything,because she knows deep down he's still seeking love and approval ,and a relationship his mum.
But it galls her that MIL has turned up unannounced at inappropriate when she's settling the little one.Seems to think her son should ferry DGC up to be played with at her house at a time that's ideal for her,not when they genuinely need help.Has a secret stash of fussy hand knitted clothes she changes DGC into when she's left with her for a few hours.Then takes loads of photos of her dressed in them.Ignores meals left when weaning,and feeds what she feels appropriate-the same cereal, spoon fed -even though DGC feeds indepently now.
In short DD said the other day 'she doesn't give too hoots about me mum,or even her own son,she just wants access to DGC .I bite my tongue and stay out of it.Mainly because the other grandma does one nursery pick up a week that I can't do.And again I still believe just because it's our daughters child,it's her partners too.I've just urged DD to take a deep breath,and as long as she feels DGC is safe not pick battles over things.In the grand scheme of things it a few hours here and there other grandma is in charge.But I know she doesn't always find it easy,and that's justified IMO.What worries her the most is that the timing of their baby coincides MILs younger son leaving for university and her having a void to fill.
It's made me realise how lucky I was with my own DMIL. Lovely kind,helpful but not at all interfering -and was very welcoming from day one of my relationship with her son.Not my DDs experience sadly.
