aha! my dm also has the knack of making me feel undermined in my decisions.
i know she only has dd's best interests at heart and i also know she adores dd as much as i do.
i have discovered that i am very relaxed about anything she says as long as i am confident in my own opinion on the subject.
if i have a niggly doubt then it's red rag to a bull!
for example, dd goes to CM 3 days per week. she is happy there but i have niggly doubts due to her getting a bit upset at drop off sometimes. also I know CM is a bit stricter than me which rationally I think is a good thing but emotionally it upsets me that dd is experiencing discipline other than mine.
not big stuff of course, just sharing and being kind/respectful of CM and other mindees etc. also dd is getting very articulate and will tell me something like "i wasn't allowed a biscuit because i was naughty" which upsets me. i then mention it to CM who clarifies that the biscuit was "delayed" until dd calmed down from a paddy or some such!
dd has a barefaced cheek and is capable of telling me "Granma said I could" when grandma is next to her and said no such thing!!!! dd is 2.5yrs and I really didn't think it was possible to be so brazen at this age LOL!
Anyways, to get to the point, I do worry a little about dd in childcare but think I am probably over-reacting. Last week DM did all drop offs as I was away on business. Now she is questioning if dd is really happy with CM. which just taps into my own issues and gets my back up!
arg! i just said "don't even go there with me on this, CM rang you after drop off every day to tell you dd was fine AND she's the happiest, smiley girl when you picked her up so there really is NO PROBLEM"
but of course, I'm also convincing myself LOL......
Gentle reminders and persuasions that it's your dc and your rules without getting DMs offside is an art IMO!
