Staggered Nursery dates so losing 15hrs free funding -can I request earlier start date ?

[HalestormRock]

Hi, My DS is due to start Nursery (5 mornings 9-12am) and the school has staggered the intake.
Intake starts on 4th and children trickle in so my DS start date isnt until 10th Sept. Therefore I am losing 15hrs funded time as he is starting 7 days later then official beginning of term time.

As a part time worker I was previously sending him the same hours (funded) to the schools pre-school meaning I had Thurs and Fri mornings for housework/grocery shopping etc.
I understand I will only be affected for a week, but feel a tad annoyed about this. I will also have to pay three full days childcare to childminder as rather then 3 half days childcare for the Mon-Wed when I am at work, so am considerably out of pocket financially too. There are plenty of SAHP at the school and many of their children are starting on the 4th - no discussions were taken regarding financial impact or childcare issues of these staggered dates for those parents who work (as usual we always seem to be an afterthought). No offence intended to SAHP purely looking at this from a practical point of view.
Would it be unreasonable, seeing as there is a gov obligation for the 15 hrs to be provided, for me to ask they allow my DS to either start on the 5th - giving me the chance to arrange on the 4th which will be my earliest chance, or request they allow him to attend the pre-school to make up the lost 15hrs.
Opinions welcomed please.

The start dates are just done alphabetically btw. At least at my school. The people in the office do it. They certainly dont take anyone's circumstances into consideration. If it doesnt work, we wait for the parents to let us know and then try to change it. It would be way too complicated and time consuming otherwise and schools are always so busy.

I have to say I can see the Op's pov. Why should she have to pay out a not inconsiderable amount of money for childcare that she is entitled to for free whilst a parent who isn't paying for childcare gets an extra week? Ideally everybody would start on the same day but as that can't happen there's no reason why she and the other working parents shouldn't be prioritised. Why does the child of a sahp need to get the free childcare first?
What the school should have done is to ask who would prefer an earlier start and then go from there.

No harm in asking.

It could be worse though! Many moons ago dds school did this for reception. All those that were not five in the first term started staggered. Fair enough. But then they also kept them part time until January. Started off with an hour a day , then two and so on until they were doing full have days , some weeks doing mornings and some doing afternoons. Eventually either stopping the morning and for lunch or coming just before lunch and stopping the afternoon. It was a flipping nightmare and Tbh the kids full time had established friendships by the time mine went FT

Northern neither parent is entitled to anything. The children are entitled to fifteen hours placement. Saying that one parent is a more special snowflake than another is just idiotic.

My child is having his fifteen hours shunted into two and a half days. I'm a non-working parent. There will be parents who have not got these hours that want them, and some of them may be working. However, it's the luck of the draw when they allocate these things and I would be sodding livid if my child was bumped from his placement purely to meet the needs of a stroppy parent.

Sorry for the delay.
Also sorry some people think I m being snotty about SAHP. Not at all - as I said in my post I was looking at this purely from a practical point of view.
I would love to be able to be a SAHM and respect them as much as I respect all other parents - we all have different home situations, however as a family we couldn't pay our bills if I gave up work. This is not about Working parents trumping SAHM parents.
Northernlurker - I am glad you can see where I am coming from.
Tigers - that sounds like a nightmare situation!
Procrast - I am not a stroppy parent. I am a parent who is trying to make ends meet under immense pressure financially. Any little cost incurred at the moment is adding further stress. Yes this is not the schools fault - however they should be providing 15hrs funded time per week in term time, and in this case they are not. Yes only by one week - but this is still having an effect on our family, logistical issues, and juggling several other factors.
