AIBU here? Currently my Inlaws who are a both retired watch my 8mo DS once a week for around 3/4 hours max. DH is working away from home 5 days a week so only home at weekends and my parents both still work full time. I really appreciate them offering to have him for that time as it means I can blast through alot of errands in half the time it would take me to do it with DS around. However, for the last 3 weeks when they have said they can't have DS because one week FIL had sickness bug the following week MIL had it then this week they had jobs to get on with that they hadn't got done while Ill. All this is absolutely fine of course as like I say I appreciate any help from them. But what's really got to me is that they have 2 other school age grandchildren they look after twice a week too to put it into context their mum which is my BILs wife does not work and children go to school full time all week and in laws have them 1 school night a week and 1 full day on Saturdays were talking 9 till 6pm. When they told me they couldn't watch DS on the days they were ill or busy on all occasions the following day they still had my nephews. Also just to add an extra element we were due to go to a wedding one Saturday ( my parents were on holiday) and they said they couldn't have DS because they have the other two children and when DH asked if they could miss this week or have them on the Sunday instead they were really put out and said no. AIBU? To think they favour these other children over ours? I know all parents may say this but DS really is a joy to be around too he is really easy going as far as babies go.
